"we count chromosomes by the amount of centromeres present" - finally somebody said it that clear; you could add to your def. that the equation counts for 1 centimorgen; btw i like your voice
I've been studying this stuff for over a year now and it's not until now I've clarified this concept out. I don't know why that's so hard for some people.
Does single chromatid contain centromere? If yes, then it is correct, otherwise, by that logic of counting centromeres, humans would have 23 chromosomes and not 46 (which is the case).
@@UkbunemalYokanlush what is your opinion on optical genome mapping?
This is just another video on recombination. There is no gene mapping involved here.
Exactly. Why are there so few gene mapping problem vids? It's so frustrating.
Recombination is a method with witch you can map genes in a chromosome. What are you looking for? Sequencing the base pairs?
Joey A yes, sequencing
You comment saved my time thanx

Yay! I get it now! More distance = more probability! Thanks!!
A good sensible reason will be more helpful 😒
1:45 this has confused me for a long time, so I just memorized it before. It's great to have a simple answer like that.
wonderful explanation but no gene mapping , bummer!
it so makes sense now, thank you!
Very good explanation! Thank you!
Best video 😭😭😭😭😭. Thank u sooo much ma'am for explanation in such detail.
Can u pls do videos on deeper genetic engineering concepts? I really love ur videos...
Thank you so much! I was getting a same question wrong again and again! Your presentation helped me a lot to understand how to solve.
that was really helpful thank you ❤️
Nice explanation, Thank you very much!
Well explained!
Really cleared that up thanks
That writing speed though!
it is really difficult to get, thanks.
Great work
This video FINALLY helped me understand this concept THANK YOU!!! lol
if the frequency of swapping over is 6% then what I don't understand is that why did it swap at all? Didn't she say that they are less likely to recombine if the distance is closer ?
Hey, then what is the extent of recombination of the blue and green genes? Is it more likelier than the recombination of purple and green?(cuz of greater distance?)
I feel the concept of greater distance thus greater recombination is false. Lesser the distance greater the transformation is true
I know I'm late, but nope. The more the distance there is between them (Linkage distance), the more crossing over there is between them (Recombination), so in other words, a recombination with blue and green would be greater because of the great distance.
very good explanation, thank you
Thank you!
So amaaaaaazing
Pls upload Chromosome walking elbortly....
Plz add extra nuclear radiation@Khan Academy
Thanks
Describe how restriction mapping is carried out
Pls can I get mcq book or web site about genetics
is it same process in autosomes as well as sex chromosomes?? will it be differnet in case of autososme?? please expain!
Anyone not affiliated with bio/science would think recombine is to put back together not separate. Lol
This is a great EDUCATIONAL VIDEO
Pls upload chromosome walking detail vedio
Best
Thank you for this video ... but I think you wanted to mean ... 6% out of 100 meiosis events recombination will happen between the two given gens ... correct? It means that centimorgan is actually a unit of time ...
I thought the same. But im not sure myself. Can you explain or confirm if possible?
The comments is 6 years apart though... please let me know if you learnt further on this topic!
Is Gene mapping and chromosome mapping is the same thing??
Yes and no. I'm a genealogist. I do family histories. So... To me, gene mapping is not the same. It's more of a relationship mapping and not necessarily as a recessive gene would be shown. i.e. mapping out classmates vs. mapping medical issues in a family
Maturity is when you realize that khan academy is not owned by khan sir
No gene mapping
Is purple pink or am i triping
If I only heard that digression in high school
Sorry to say....but impo. Also...Are you gone mad continuosly saying purple colour to magenta and pink
RITIKA CHAUHAN why does it even matter?
Well aren't you rude.
Is it just me or is she chewing gum ?
Talks too much..
Not on poin most of the time.
this is crossing over not gene mapping. you wasted my time
I´m sorry, but the video is talking about chromosomes and chromatids for 3 minutes until it gets to the point. Please get to the point, we wouldn´t be watching the video if we didn´t know what a chromsome and a chormatid is/ look up gene mapping to begin with!
not good...worst
