Using data from a three-point test cross, this tutorial show how to determine the order of the three gene, the distance between them, and the degree of interference.
people like you on youtube make me rethink paying thousands of dollars for classes at a 4 year University. You made something I had no grasp of extremely understandable in a fraction of the time I've spent on our course textbook software and online lecture tools. Thank you so much.
This is a resource for my class at the 4-year university where I teach: Samford University, Birmingham AL. We'd be glad to have you in our Biology department. 😁
My head was jammed before watching this. Calmed my mind and watched the whole video. Everything is clear. Now I am able to solve more problems like these. Thanks Professor.
Much appreciated! You've taught me more than my lecturer and tutor in these 32 minutes than they have in the past 4 weeks. Thumbs up!! Hope you have a wonderful day Sir :)
omg. i wish you were my professor. I sat in the lecture for 2 hours, but had no idea what my professor was talking about. But i got the concept less than one minute after watching your video. Thank you so much
Sir, you are brilliant in all aspects of teaching. Your lessons have truly left a remarkable impact on my life, and with that, I hope to pass on your teachings to those around me in an effort to spread knowledge and positivity. I hope all goes well for you in life and I hope that you truly understand the significance of education that you helped spread across the internet. Thank you.
Thank you so so very much for making this video, I have been struggling with this concept for two semesters and yours is the only video on UA-cam that laid it out so plainly and without confusion! Keep up the great educating!
You did such a great job explaining this. I have been scouring the internet for a video as good as this one and I am so happy I finally found it. You are an amazing teacher, thank you so much.
Honestly, thank you so much for posting this video. My professor did not explain this well at all, and you made it seem so simple! Here's to passing my Genetics exam tomorrow!
Thank you so much! My professor went over it once in class and never again so it's going through and finding things like this to help teach myself that got me through and made me successful in the class.
I have searched for more than 50 videos on this topic because I am an absolute beginner. YOUR VIDEO IS THE BEST !!! and really helped me. Thanks for such a detailed explanation. Loved it !! Thanks a lot
Seems like you took your time! sometimes my professor is too fast in explaining topics this one explained it on a deeper and easy to understand level. Thank you for helping me understand this better.
THANK YOU so much sir! For some reason this concept was very difficult for me to understand and I tried to watch many videos that just didn't help at all, however, this one was so clear, easy to follow, but still very detailed. I appreciate it! You are a great teacher! In just 30 minutes you touched on basically every important thing related to three-point test crosses. Wish you were my professor!
Thanks, Professor Dr. David A. Johnson, You have explained so very beautifully that I am in awe of understanding this concept which eluded me throughout the week. May God bless you and keep you safe in these trying times.
This video helped me to understand the concept of three point test cross and solve problems from CSIR NET question papers. Thank you sir for describing it so easily. Looking forward for more videos.
thank you for making this video! I was struggling with my assignment and looking for some explanation videos and I come to this video and this is really help me, finally I can solve the problem in my assignment.
My god, the man fixed those percentage errors last minute! Props to those catches! Great video! (For any of those confused about what I'm referring to: he wrote 45/1000 = 4.5%. In fact it equals 0.045%.)
Wow, Thank you so much ! Oh, I wish that my lecturer at least may learn from you regarding how to teach well and how to guide properly without wasting time!

My god, the man fixed those percentage errors last minute! Props to those catches! Great video! (For any of those confused about what I'm referring to: he wrote 45/1000 = 4.5%. In fact it equals 0.045%.)
A little basic math: 45/1000 IS 4.5% (This is 4.5/100 which is 4.5%!!! Per cent is parts per 100. 4.5% = 0.045)
Ah my bad! You are indeed correct! This video helped me for my Biology Final, thanks again!
