Genes, jeans, inside or out?

Designer genes clearly aren’t blue
imprinted, they’re inside of you,
inherited . . . give us our due.
Coded heritage--each unique--
don’t know what to expect! Let’s peek . . .
colored by number . . . every cheek.
No living being lacks these genes
whatever their birthright or means.
Even our tastes . . . do you like beans?
Are you athletic . . . can you run?
Are you outgoing . . . love your fun?
When everything is said and done . . .
designer genes are hand-me-downs.
What’s your family history? Clowns?
Do you have shadows of worn frowns?
Our sex is the first thing they choose,
then all our colors and their hues,
our emotions, perhaps our views.
Marry in passion . . . few do stay.
Some have a tendency to stray,
don’t want to part . . . just want to play.
Maternal genes compose the brain;
paternal favor what we gain.
Designer genes are never plain.
