Biology 2

[Intro]
"Hey Lisa, they're having a big party
Down at the Allele Pool tonight!"
"Oooh, let's do it!"

[Verse 1]
You will put your good traits in
You will throw your bad traits out
Do the Homozygous as you shake 'em all about

[Chorus 1]
Unless you've got your dominance
Down in your genes
You'll have a kid, invalid
Just like Mendel's beans

[Verse 2]
Oh, hold me, you know
You are my one and only phenotype
Yeah, and together
We could have a genotype

[Verse 3]
Darwin willed that
We would do or die
Brains and brawn are
Both in great supply

Kalikaks a-swimmin' back
And forth will multiply

[Chorus 2]
You could choose your ancestors and grow just like a weed
Pick a stud to congeal your blood and get your earlobes freed
