@@thegoonerz thank you for the offer but after a few times watching the video i finally got it (the part where you figure out which gene stays in the middle) .
This was sooo helpful! I kept coming back to this video while I was practicing problems, and know I finally understand this concept. I haven't understood it for months lol I'm so grateful, thanks so much for your help!!!
generally i donot comment in vedios but here i am commenting to make this type of vedios more and more and i pray god to bless you and thanks you to help me the night before the exam......
Sir, how you deduced that the 14cM is the dist btw a&c gene and 9cM(b&a gene)? I didn't get it....Why not the reverse?Can you please explain me? I would like to learn...
No I was trying to solve a like problem and luckily I was able to solve only with your above two videos explanations but since I was trying solve question with answer given, so I though that I may be right in putting the above formula for farthest alleles....and so I inquired about it. Thank you so much
Bc a is the only gene that changes while c and b remain the same. the gene that is in the middle--- has to change while the other two genes remain the same
this video just confused me even more with the concept changes from the first. How is A in the middle when a double cross over would have to be c+b and +a+?
I learned that, C.o.c = observed d.c.o./expected d.c.o. ... And I can not relate your said c.o.c formula with mine... Can u please tell me are they both same?
We know that "observed" DCO are 4 + 2 = 6 How do you calculate "expected" DCO? For DCO to happen both SCO 1 and SCO 2 must happen (Product Rule). Therefore we know that (46+38+4+2) out of 1000 (0.09) SCO-BA happened x (71+63+4+2) out of 1000 (0.14) SCO-AC happened. So the probability of DCO == (0.09)(0.14) = 0.0126
This one explained how to tell what the middle gene was much better than the previous one. Thanks!
I still have a hard time understanding this
@@eiskola7811 Which part? Perhaps I could help :)

@@eiskola7811 nice 😉

LIFE SAVER THIS IS THE VIDEO U NEED GUYS IF UR STRUGGLING DONT LOOK ELSEWHERE
who in their right sense of mind will dislike this video. Very well explained.Thanks
Best example I have seen thus far, direct no bs no stalling just straight to the numbers
This was sooo helpful! I kept coming back to this video while I was practicing problems, and know I finally understand this concept. I haven't understood it for months lol I'm so grateful, thanks so much for your help!!!
Very good! Glad you've got the concept now.
Finally cleared my doubts on DCOs and COC and Interference in a single video. Thank You, 💯
Thank you, this saved my life.
as a senior bio major, this is the most beautiful video I have ever seen

Thank you for the kind words!
Thank you! Best doublecross video I have seen !
Both videos were extremely helpful, thank you so much
I finally understand what to do!
I understood this video a lot more than the last one! My grade for my exam tomorrow thanks you!
Glad this helped!
You saved my life THANK YOUUUUU
Thank u teacher.u saved my exam💌
Thanks a lot 😊
wow! This made so much sense. Thank you!
Thank you for the helpful video!
Amazingly explained.
realy clarifying my concepts.
Excellent video 👍
Thank you.. Please solve more problems on this..
Again, BRILLIANT! Thank you!
thanks man u save my life :D
I'm confused by why you changed the parentals and then it went back to what you wrote before at 4:48
Why do you have to add the double crossing over (in this case 6) when calculating the distance between the genes?
thank you so much huhu
best video
Thx Kevin
Did I miss that the double cross overs are 2 not 6? for the COC
Thank you so much !!!

I am wondering the same
Thank you!!!!
The distance between b and c is - all SCOs/1000 * 100 = 21.8 cM and not simply 14+9=23
I believe you are right, the DCO's have to be ignored for that bit. do you have an exam today as well?^^
No I was trying to solve a like problem and luckily I was able to solve only with your above two videos explanations but since I was trying solve question with answer given, so I though that I may be right in putting the above formula for farthest alleles....and so I inquired about it. Thank you so much
How do you see which letter is in the middle when you don`t have dco?
How do u know sco1 and sco2 is the distance of ac ?
thank you!!!!!!
How is a the middle gene when b also changes and stays the same? I'm sorry but confused at this video. Please can someone answer for me.
Bc a is the only gene that changes while c and b remain the same. the gene that is in the middle--- has to change while the other two genes remain the same
So confusing that you went back and forth from +/A +/B +/C
this video just confused me even more with the concept changes from the first. How is A in the middle when a double cross over would have to be c+b and +a+?
Do you still use the same approach if you only have two data of SCOs(SCO1,SCO2) instead of a pair of SCOs(SCO1~4)?
you can probably extrapolate the missing data
I learned that, C.o.c = observed d.c.o./expected d.c.o. ... And I can not relate your said c.o.c formula with mine... Can u please tell me are they both same?
We know that "observed" DCO are 4 + 2 = 6

For DCO to happen both SCO 1 and SCO 2 must happen (Product Rule). Therefore we know that (46+38+4+2) out of 1000 (0.09) SCO-BA happened x (71+63+4+2) out of 1000 (0.14) SCO-AC happened. So the probability of DCO == (0.09)(0.14) = 0.0126
very confusing compared to last video concepts changed
Thank you so much !!
