Linked Genes

Paul Andersen explains how linked genes behave and how linked genes were discovered. He shows how linked genes would be reflected in a dihybrid cross using a fruit fly simulator. He uses chromosome-based punnett squares to explain why the frequency of recombination is less that 50%. The actual crosses discovered by Thomas Morgan and Alfred Sturtevant are included.

Never thought I'd be back at his channel in college, yet he still did a better job explaining this than my professor.

Honestly the only reason I'm doing alright in AP Bio. X"D Thanks so much for making these hard topics easier to understand!

[@emmelinejoseph7433]

Wow! I finally understand what linked genes are. Thank you so much for this video. You saved me for this bio midterm tomorrow!

[@xfatality1]

I did this in high school too. I would sleep/not pay attention in class at all and the night before i took a bio test I looked at a few of your videos about 3 times each to fully capture everything you say and retain it and end up receiving an A on my test. Because of your help, I am able to bs my way out of biology :D

[@vedantbhardwaj7582]

aahhhh I watched you during my high school days, and yet again I'm watching you for my med school exams again!!! One of the best!!!!!!

Okay so I literally just created a KZbin account a minute ago just to thank you Mr. Anderson for these videos. Everything makes sense now. You should be my professor. I came from the Galapagos Islands 2 years ago and it's kind of hard to understand all these terms and concepts but you make everything seem so simple and I actually understood every single thing you said. THANKS!

[@bittersweet1789]

I have been watching your videos for half the semester now. Thank you so much. They are extremely helpful for my course!

[@yanetbenyam2226]

I DONT KNOW WHAT I WOULD DO WITHOUT YOU! thank you soo much.

[@tosinibrahim5079]

I have to say that your videos are amazing!! You make things a lot easier to understand. You're well appreciated.

[@annadrake9428]

[@BigMarquise]

Generations of Biology students were saved by this man. I suppose I am the latest generation to discover this video.

[@Marobobb]

My teacher didn't even understand this. God bless you and i can't thank you enough!

[@fleshcookie]

beautifully explained. I'm in a 300 level genetics class at a major university and this is just spectacular. This is a very difficult concept to grasp just reading out of a textbook, and having a professor who simply reiterates what the text says doesn't help. Mr Anderson, You the man.

[@dilarad.5640]

You are amazing. That helped me on my class very much. Greetings.

[@noblekpante6215]

this guy is a life saver. I thank God I have found you early enough to help me through my biology class...I almost redrew from that class. Do you have tutorials on lab as well? Thanks a million times. I wish I had money to donate to support your course.

[@oshinshukla8527]

This makes perfect sense. THANKYOU SOO MUCH!! i have LITERALLY struggled to understand this for almost a year now.

[@faramund9865]

These lessons are great! I've always "known" genetics weren't as simple as the Mendelian theory we learn at high school. But I never found a more advanced explanation of genetics, and here it is! That's just great!

[@lorenas7410]

I understand better biology with your videos in English than in my native language when my croatian teacher explains it,thanks a lot Mr.Anderson :)

You're an amazing teacher !!! I watched 10 other videos and I didn't understand the concept... I finally understand it :D I wish you had a video about gene mapping
