Teacher A: Is there much variation when you’re doing asexual reproduction?

DCM

Student 1: No.

 

Teacher A: No, ’cause they’re just making copy after copy after copy. And so the only chance of genetic recombination would be a mutation. But when you have sexual reproduction, it increases the chances of genetic variation [Teacher A further explains using her deck of playing cards.] If these are Mom’s genes, and these are Dad’s genes [holding a half deck in each hand], and you shuffle them together to make babies, then each hand that you deal is the babies’ set of genes that they end up with.
