ccpp is white because the precursor(raw material) is colorless which is same as white due to absent of two required enzymes C and P. Only one genotype will produce purple color which is CcPp or CCPP that has both of the enzymes. The other three genotypic classes (Ccpp, ccPp, and ccpp) that doesn't have both of the enzymes and only has either one of the enzyme or no enzyme at all, become grouped together with respect to phenotype and express no color(the color of precursor) which is white. so yes she is correct ccpp produce white color which is same as no color of the precursor.
You cleared my doubt
ccpp codes the precursor i.e. white. In ccPp also it codes white. Then why shouldn't it get into purple as it has the dominant P?
I have also a doubt in this case..ccPp should take colour purple..Shouldn't???
@@MdNuman-ij1fu no it won't produce purple color because it is a case of complementary genes so when both the dominant genes are present together then only a purple-colored flower will be produced.
@@meenupriya8282 To get purple colour, both C and P must be present.......missing of any one of the both dominant allele will result in recessive expression...that is white.
Madam I am getting addicted to your lectures..thnk you so much mam.☺
Actually
Yes.......... didi..
I guess Im asking randomly but does someone know of a trick to get back into an Instagram account?
I stupidly forgot the password. I appreciate any help you can offer me.
@@juliusjeremy4723 yep you can get back your instagram...not to worry...just open your instagram there you will see the "forgot my password"option click on that after clicking on that they will send a otp to your message just put the otp on the space provided in the instagram then click the done option...or but also if it's not working instead of clicking done option click back option there you will find your email just click over that then go to the gmail then..you will definitely get back your instagram...I hope so it helps you...
I just want to know whether Multiple Allelism, Pleiotropy are all part of intra allelic interaction or not ? Because you started with variations from Mendel's Principles in the previous video, is this all in continuation with it or an essential part of it..?
i think in the 1st row 3rd Coulomb CcPp will be CcPP , Although for this nothing will be change in color . LoL
KinG Arnab
Yeah..😁
I don't know if you read comment or not , but thank you so much for your explanation , it really helps ^^
I don't think she does
Thanks a million mam!
08:32 Mam, on the punnett square the 3rd offspring should be CcPP
Thanks madam...
Understood it after 5 years 😍
In complementary gene interaction when two dominant alleles come together in F1 then they express themselves resulting in the formation of new phenotypic trait. But when they are away from each other there expression is masked by the recieve alleles, a phenomenon called as duplicate recessive epistatis. Therefore, Bateson and Punnet crossed two varieties of Latharus odoratus CCpp x ccPP they were both white and their F1 yielded CcPp (Purple
flowers a new phenotypic trait). The F2 offspring were in the ratio 9 purple : 7 white.
Abrar Yasin but I think this is co dominance that you are telling
in complementary gene no new phenotypic trait is formed but in collaborative gene is where new phenotypic trait is formed
a
Abrar Yasin yes you r right
Excellent lecture madam.....Most helpful
Thank you very much, i was giving up on this topic because i couldn't understand the notes and i couldn't find a video of AK lectures on this topic, but thankfully i found this video and everything flowed into my brain. Thank you
Mam thank you so much. Your teachings are so helpful to me to prepare for NEET
Great teacher we saw till now..🙏
Keep continue it mam
Your video is so much helpful for all of us
Thanks for your lecture mam
Thanks
Real the way your teaching is amazing thank you madam❤
That was heck of a good lecture
great video! thank you, my professor didn't explain this well but you really helped me understand.
Awesome mam
I just started watching ur videos ytday and Im getting addicted to it already
You r osm at teaching.. forever thankful to uh mam♥️
🏮ONE DOUBT? - Mam, what will be the colour expression when ccPP combination of gene occurs, will it be white? But, cc - is recessive??
Yes...it will be white as purple will be expressed only when both of the dominant alleles ...that is C and P are present...., Missing of any one of the both will result in a recessive expression that is... white.
@@likhithaudayagiri8891 But how ?if ccPP is present then that means chromagen(white) will not manufactured , then how white color?
@@gsbrar1496 because the the raw materialis also white
Thanks you
Thank you, Ma'am. 🙂
Mam ur teaching is osm😍
There is a mistake mam before crossing means in f1 result when we come we take both the white colour of flowers either male or female, .but in the video u described it as purple and white when crossed shows purple which do not shows complimentary gene characters
Mam please make vedio on additive gene and inhibitory gene
Thnku so much ma'am ❤❤

how is ccpp white although c is not dominant
Monojit Bhattacherjee
it is not ccpp, it is ccPP. here cc is epistatic to PP, cc is masking the effect of PP allel. Thus plants with ccPP alleles will also produce white flowers. However cc is recessive to CC and CC itself is recessive to PP. so when a cross is made between CCpp (White flower) x ccPP (White Flower , as cc is epistatic to PP that is why it has white flower too). In F1 we will get CcPp (purple flower) becoz here C is dominant over c, make it unable to have epistatic effect on P. However, C itself is recessive to P, therefore the purple colour we get in F1 is due to presence of PP alleles. Complementary gene action is therefore also called as Duplicate Recessive Epistasis
Abrar Yasin thnku so much
sir i also agree with you , in the last is dont mentain the reaction , for white color we must need the Dominant C for activate the enzyme A ,,
ccpp is white because the precursor(raw material) is colorless which is same as white due to absent of two required enzymes C and P. Only one genotype will produce purple color which is CcPp or CCPP that has both of the enzymes. The other three genotypic classes (Ccpp, ccPp, and ccpp) that doesn't have both of the enzymes and only has either one of the enzyme or no enzyme at all, become grouped together with respect to phenotype and express no color(the color of precursor) which is white. so yes she is correct ccpp produce white color which is same as no color of the precursor.

Happy doctors day mam✨✨✨✨
Yeah ....tq for informing 😍 ...
Thank you so much ❤️💕💞❤️🤗
Fantastic
Mam love u
😍😍😍😍only bocz of u i m able to com... whole of the my sylabuss as soon as possible 😇😇😇
after a huge search i gotten the answer of my doubt.Thank You Mam!
Mam please upload a video regarding "lethal alleles " with types and respective examples . I tried hard to understand the examples in books but still confusing.Thank you mam.
You are fantastic nbio queen
Mam thanks a lot...Your explanation that means pronunciation is extraordinary.
Thanks a lot mam!!!!!
Thankyou ma'am 😇

Thank you so much for making this vedio, I can't study anything without understanding, this video helped me much
Thnku you 🙏
how come white colourd flowers are produced when c is not dominant and it doesnt produce chromagen?
In short to form a purple there should be at least one C and one P at the end ratio will be 9:7
very good explanation.. Thank u mam..
Mam,C must be present for white colour but when it is ccpp we are saying that colour is white but how...... C is not present ? For enzyme 1, C must be present.
Great explanation 💓
Very nyc ...way of presentation ..
Thanku mam
Love u alooooot mam
Is it in the syllabus of neet... Like there three random topics... Complementary genes and all 3 after that????
Thank you so much for the videos mam.!

U R really fabulous mam😱😱😱
Lots of ❤️ and respect from Kashmir
Mam what's the difference between polygenic inheretenc and complementary genes?
Madam, I didn't get the concept of ccPP
THE PURPLE COLOUR ONLY SHOW WHEN THE BOTH CHARACTERS HAVE AT LEAST ONE DOMINENT GENE !
This will be white as both enzymes are not produced properly so the flower is colourless which is same as white
Yes, both genes C and P must be there to produce colour
great job mam
Madam is complementary gene interaction always have ratio of 9:7
Mam u r really world's best tutorial teacher ❣️ I'm totally addicted to ur lectures!!😇

Hi mam is the marker gene and selectable marker is same
Oh my God.. You saved my life!! I'm a high school student and I watched too many videos about complementary genes but it was in vain and I started to lose hope.. But when I passed by your video, I could understand it very well!! Very detailed explanation and an attractive style of teaching. Now I can do well!! Thanks a lot!!

Mam gene C whether dominant or recessive ... Is it always code for white?.... Or if recessive then it will not convert rwa material into pigment??? ...... Plzzzz clr mam

Mam can u plz provide lectures for CSIR NET life science????
Agar c vi recessive hae to white kaese hoga
White and colour less mean the same thing here ...she forgot to mention it ...
Thus, chromagen and raw material both are white even if they say raw material is colour less....
ccpp and Ccpp both are called white itself ... Or
White= Colour less
This was mentioned such n my book
Didn't Understand Why ccPP Or ccPp Will Be White Bcoz First Enzyme Produces White And Both Purple, But In This Case There Is Only Second Enzyme Not First, Also Confused Why ccpp Will Be White Because Enzymes Are Absent But White Chromagen Requires Atleast Cc Enzyme
Colour less also means white so chromagen and raw material is white tho they say colour less.... She forgot the mention it but it's there in my book
Thnayuu mam
Mam you have made a mistake that in 1st row 3rd column it should be CcPP
Thankyou so much ma'am u explained very well 🧡😊

Mam please give a lecture on isoallele and pseudoallele.
Ma'am u r toooooooooooo gud😁😁😁
Thanks maam
In f1 oppspring can't be 16
Please reply mam
Thanks mam
ccPP how the raw material convert to anthrocyanin is it dirctly convert without white colour formation or white colour is formed than purple
White k liye bhi to C enzyme chahiye
Phir jab dono small honge to kaise white hoga f1 parent me
thank u so much mam and for that reaction..now i will not forget this
Damanpreet Kaur hi
How is ccpp white coz enzyme 1 is absent so raw materials dont form chromagen....so the flowers should be transparent or something?
Actually chromagen is a colourless pigment ...N by white ,we mean colourless...
mam ú make conçepts very easy .țnk u so much
thanku mam
Maam sound is not clear....
thank you so much mam to give us such informations. we all peoples are thankful for that. But plz tell us that how ccpp (parent) will be white Bcz here cc is not dominant also the chromagen will not synthesis so how they can become white??
Actually by white,we should mean colourless n moreover chromagen is a colourless pigment.
tysm maam ...very helpful😊
