Genetics: Linkage Problem #1: Map Distance, Coefficient of Coincidence, and Interference

[@keiraalbano2184]

You just taught me 2 weeks of genetics in 12 minutes. This is amazing.

[@alandriaglenn3145]

I was literally just going crazy because I have an exam coming up and I was so lost even after watching all of my professors lecture videos. You made things so simple and straight to the point THANK YOU SO MUCH!!

Wish you were teachiing my genetics class. Thank you for the clarity.

[@cheeseEmonster]

I never comment on these things, but this was the BEST VIDEO related to genetics I have ever seen.

[@alyhoney9338]

Made my professor look like he was overcomplicating EVERY step. Thank you!

[@sophiad123]

I have been looking EVERYWHERE for a video explaining double crossovers and linkage like this. You explained it perfectly to me, I feel way more confident on this subject! THANK YOU, THANK YOU, THANK YOU!!!

[@CatalystUniversity]

You're welcome~

[@Hammie5105]

The billion dollar question was the question I needed answered to solve all my problems

[@sphuxisanime6382]

My lecturer couldn't help me understand this in 1 semester and you did it in 12 minutes. Thanks a lot you are a life saver.

[@myforever13]

i have been confused on how to figure out which single recombinants go together for weeks. and here is this perfect video that makes me understand. thank you! i dont know what i would do without vids like this

[@mtado4933]

hey, thanks for the explanation, amazing video, to the point and informative and blah blah blah anyways i love you now.

[@matthewcardenas5124]

I like how a 100k tuition lead me to a free KZbin video and 178$ book!

[@sierra5726]

I thank you from the bottom of my heart because you literally might be the reason I pass my genetics exam. This tiny moment of relief gives me hope that I can and should remain in my pre-dental program. Thank you so much.

[@CatalystUniversity]

I'm happy this video was able to help you!

[@HANACANHASI]

[@thegoonerz]

I cannot leave this without saying thanks. Tomorrow is the exam. You explained it really well. Thanks, Sir.👏🏼

Thank you so much for the kind words, Ankit.

[@danielpinchas5972]

This was by far the best genetics video ive seen so far on youtube. clear and good explanation. thank you

[@legenarymaster3696]

You are absolutely amazing. Something made so complicated by my teacher is beyond simple when explained by you.

[@nowshadnoman4856]

My sincere gratitude for your generous assistance. Your support has been invaluable, and I am truly appreciative of your guidance. With warm regards from Bangladesh

[@redispink5784]

You are a godsend! Thank you so very much! I have the worst professor right now for my genetics course. She is never in her office hours when she says she has office hours, and the way she explained this problem in lecture was so confusing.

[@aireenshazwani1403]

you saved my final marks, no words could describe how grateful i am *cries

[@Ari-jp7kt]

You saved my life and now you are my dad (2) Thank you so much

[@michaelachampagne5260]

I never comment on anything but you just made my night. I had no hope of figuring this out on my own!

[@naomives96]

Isn't the +b+ a double crossover if the parentals are +++ and abc? I don't get it.

[@nicoleouellette2694]

THIS. Thank you for making this video, so much more helpful than a professor posting lecture videos or reading the textbook.

[@simplyfishingdk7148]

This man is a miracle worker 🙌

[@bt-poulomibanerjee7371]

ohh my god!!! I was so confused with this topic before I watched this video.....thanks a lot sir !!!

[@esahoosa]

Omg so helpful! Was trying for a while to figure this out, never thought it was this straight forward :0

[@CatalystUniversity]

Thank you!

[@zerowolf137]

This is probably the best example of a 3 point test cross. I was so confused.

[@williammango80]

[@adrisha7520]

[@jacquelinealipo-on4040]

May I ask why is a is in the middle? I don't understand why because letter B is in the middle in phenotypes. Thank you.

[@AriannaGama]

This helped so much, I finally understand!! THANK YOU!!

[@graysongretzinger951]

Youre amazing man. Only got tripped up once and I missed the lecture for this.

[@effielevenson5986]

I have my exam tomorrow and I understand this so much better now! Thank you!

[@xxxxxv_lll]

Thank you so much for this video. I’m gonna have an AP bio test for genetics soon and I was going over my Mastering Biology and came across questions similar to the ones in the video. I was wondering how the answers were 12 and 5, but your explanation helped a lot.

[@kyleisbored7465]

Hold on. Correct me if I'm wrong but centiMorgans aren't additive so you can't just add the distances between C and A, and B and A to get the distance between B and C. Thanks for the video, btw.

[@KrishtiBhattacharjee]

Thank youu!! This is a life saver. Unfortunately, i still have to apply the complicated and longer methods in my exams... But this actually helped me understand everything. I feel like a weight has been lifted!

[@davideisenstadt3745]

[@summerfatima2525]

Thank you for this video it explained things perfectly ! I admire the amount of detail you put in - whether that’s noting coc formula computation gives error from math to having to add individual subunits for total centimorgan length … everything is mentioned ! You are an excellent teacher and just gained a new subscriber ~

[@wikparla8408]

This is so well explained. Thank you for this video !

[@nyluong5427]

Very helpful! Thank you!

[@CatalystUniversity]

[@isaiahdrye218]

Thank you for being a real teacher ❤️

[@maryjoe6918]

Thank you so much. Clear explanation. God bless !

[@Phyto.]

Thank you so much!!! After hours upon hours of struggling, it finally makes sense thanks to you! Liked and Subscribed :)

[@bijitchakraborty4463]

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?

[@sehrishbashir7002]

This was truly amazing!! Such Profound explanation!! Thanks alot!

[@CatalystUniversity]

Thank you!

[@Anthony-dy2cv]

I don't get how to determine which gene is in the middle. I can follow the steps but I don't know why these steps are supposed to make sense

[@rose-rb6ii]

A BIG THANKS TO YOU SIR!

[@dogedoger2606]

Thank you so much for this explanation!

[@anoncurry5004]

[@CatalystUniversity]

Thank you!

[@James15412]

thank you!!!! you saved my life

[@ravidurangala6044]

very clear explanation.. thank you very much.. keep it up the good work

[@Sluggertherunner]

Thank you! This was perfect!

[@shelbybowles782]

why would you not calculate the distance between B and C instead of adding? the mu will not always add up to be the same and you could potentially get the answer wrong if you just add the distances between A and B and between A and C to bet the total distance between B and C.

[@danishaslam8063]

Why do we use distance in M not in cM?

[@uroojkhan2447]

Thank you sir 🙏 you helped me alot❤

[@alexu176]

Bless, you didn't explain what meiosis is and helped me visualize what's going on! :D
