"Hey Lisa, they're having a big party down at the Allele Pool tonight!"

"Oooh, let's do it!"

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
