This lecturer is truly engaging, informative and entertaining. The clarity of the presentation meant that I learnt a lot and now understand much more than I did before the start of the lecture. Thank you so much.

Gosh, this insanely good video only got 30000 views?! MIT should reflect on their advertisement! I literally watched more than 500 college-level videos offered by MIT and other prestigious institutes and this single one is among the best! Since my comment is highlighted by the stuff, I'm gonna explain briefly why this video is so damn good. Dr. Eric Lander perfectly blended the story-telling into the lectures. He talked a lot of interesting anecdotes like Darwin's unfortunate ignoring of Mendel or Chagarffe's sarcasm on Watson and Crick (another gorgeous video). Admittedly, a lot of people have tried this pedagogy but ended up in distracted and unimpressed narratives. Dr. Eric Lander, on the other hand, arranges every piece of historical events and experiments in a smooth, interactive and uncompromised way that makes the audience easily engaged and appreciate the beauty of biochemistry/genetics. I also highly recommend 6.042J 2010 fall series (math for computer science). Another super-doped series. I literally cried and stood applauding at the end of that series. What a show.

in all honesty i would sit and watch your videos everyday, these are some of the best lectures i have ever experienced. MIT is my dream school. I hope this professor is still around if i get in.

[@laddis6331]

I know I won't fall asleep in your bio classes. You are pretty damn good at explaining complicated stuff in simple and clear way.

[@bandaramkesavaprasad7967]

Energetic, teaching with suitable black board work and basics. Very happy to learn from such teachers.

Love this guy :D great lecturer, very entertaining!

Page 361 He suggested that changes in an individual are acquired during its lifetime, chiefly by increase use or disuse of organs in response to "a need that continues to make itself felt", and these changes are inherited by its offspring.

Thus the long neck and limbs of a giraffe are explained as having evolved by the animal stretching its neck to browse on the foliage of trees.

He is a amazingly incredible lecturer...... BUT he shouldnt have finished the lecture without giving an answer or even any hints related! Argggggg Im dying to hear the answer Anyway, I always thank MIT opencourse and professor Lander for sharing this amazing lecture in public. Thanks a lot =)

[@sarthakparashar7508]

Better watch the next lecture then, where he answers your question :) kzbin.info/www/bejne/pZCUlYesqN-Jars

[@mariakarissalanza1013]

Professor Lander can we ask for a copy of Mendel's original paper?

[@mitocw]

You can find an English translation on www.esp.org/foundations/genetics/classical/, but other language translations can be found elsewhere on the web. Good luck with your studies!

What if juan fateen Read this com menit(logeshwaran) the studi school

[@quasarprashant]

01:59, Is Green(GG) dominant over yellow(gg)? How!! In our textbooks I'd read that yellow is dominant..

[@sambitsengupta]

green is dominant trait

[@josephd.7932]

Different trait! Green pod color is dominant, yellow seed color is dominant.

[@willsonbasyal7883]

ooooooooooouuuhh, A CLIFFHANGER!!!

[@alejandrocanales8183]

soo... anyone got any ideas about that last question?

[@MrMagnus626]

Genetic recombination (crossovers)

[@sarthakparashar7508]

Yup, he answers that here :) kzbin.info/www/bejne/pZCUlYesqN-Jars

[@swegattyswooty9307]

isn't green color recessive​

[@aduxvemus6534]

Yeah he made a mistake

[@AdityaKumar-bi1ge]

@@aduxvemus6534 no, green pod is dominant, yellow seed is dominant

[@vaibhavsharma9566]

why did professor, show green seed color dominant over yellow, yellow seed color is dominant over green.

[@swegattyswooty9307]

Vaibhav Sharma he was talking about locus .. i,.e, pod colour(G,g) not seed colour

[@vaibhavsharma9566]

Thank you.

[@swegattyswooty9307]

Vaibhav Sharma iam studying 12 th in India . I can see how you stumbled here .. nice..:-p

[@vaibhavsharma9566]

Ah, I am also in 12th standard mate New Delhi, thing is I didn't want to carry on this stupid conversation, but now if you have stated it then please listen, no, he wasn't talking about the pod colour because if it would so, then it wouldn't be in a dihybrid cross, have you ever read, round and green pod, he was talking about about seed only, fact is, although yellow is a dominant colour in seed (according to ncert) But you must have observed that almost all seed you find will be green, reason behind that is, Yellow is not for colour it's the gene for breaking down colour, so the recessivness is the gene's ability to break down the green colour, if it would have been a complete gene it must be a yellow seed. Google it.

[@vaibhavsharma9566]

professor just made all this complicated genetics more precise, first i was also unable to accept this change but then i googled it, and talk to geneticist, hopefully i have one in home, anyway, GOOD LUCK.
