In class today, I learnt - That traits are carried through, Passed from parental persons, From eyes, of brown and blue.
My nose was from my mother, And hair (at least I'm told) From father, in his glossy youth, But now he's rather bald.
My teacher called the link our genes, Not to be confused, With jeans found at highstreet shops - These are given, not perused.
Two sets of DNA, Characteristics, form, or type - Bound by lots of letters, From each parental stripe.
Genes are our beginning, Cast from double spool of thread, Back in neolithic times, In a neolithic bed.
Deoxyribonucleic acid, Tells the cells just what to be, That's why I have such knobbly knees - That dad donated, thoughtfully.
