All living protoplasmic cells That make up frogs or pimpernels Or men or hippopotami Have portions known as nuclei. Within these microscopic homes There lurk our fateful chromosomes, Those strange hereditary factors That make us good or bad actors, That shape our lips and chins and eyebrows And predetermine fools and highbrows.
Poems for Penguins, and Other Lyrical Lapses - Heredity, Greenburg. 1941
