About 1000 10-bp primers differing in sequence were obtained from Operon Technologies (Alameda, CA) to screen the parents for amplicon presence (+)/absence (-), but only 370 of the primers produced an amplicon bimorphism
He is recognized as the discoverer of isomorphism, bimorphism
and polymorphism in crystals, and he established the foundation of a chemical-crystallographic mineral system.
But the chromosomal basis of sexual bimorphism
is a matter of how we are built.
