DUDE THANK YOU SO MUCH- I have a Biology test tomorrow and this is the first resource I have found that can explain the differences between chromosomes, alleles and gens

It is refreshing to listen to an instructor calmly and confidently share such an important group of lessons. Thank you so much for your videos. Although my students are middle school, these lessons taught them at the level they could comprehend and are gifted enough to fill in the gaps.

These people teaches so well that you do not even need to write genetics like tough subject on paper. Thank you very much for uploading such videos and clearning our confsions.:)

Thank you for the first DNA/chromosome explanation video that included diagrams of proportions and where everything is located!! Not even my university class did as good of a job explaining it!

Dude, I've been looking for videos to explain these very basics but all they talk about is the DNS, so thanks for giving me a heads up on these things!
