Biology 2 - Sparks

You will put your good traits in You will put your bad traits out

Do the Homozygous as you shake them all about

Unless you’ve got your dominance down in your genes you’ll have a kid, invalid

just like Mendel’s beans

Oh hold me, you know you are my one and only phenotype

And together we could have a genotype

Darwin willed that we would do or die

Brains and brawn are both in great supply

Kalikaks a-swimmin'back and forth will multiply

You could choose your ancestors and grow just like a weed

Pick a stud to congeal your blood, and get your earlobes freed
