  • Thank You SO Much

  • Wow, thank you so much. I wish you taught in my school. Your technique is amazing. I have watched almost all your videos about DNA. You should really write a book with videos. Thank you again

  • I wish I was in your class:(

  • my dog has a small tail is it a mutation or what lol...

  • frogs with 2 legs are normal ?

  • I like the gumdrops, but i feel like the expert was sort of insincere.

  • thanks...:)

  • this is oversimplified and doesn't really explain anything.

  • When there's a positive mutation, more information is gained than lost. Right.
