title: Lateral asymmetry in human constitutive heterochromatin: frequency and inheritance.
abstract: The relative frequencies and types of lateral asymmetry found in chromosomes 1, 9, 15, 16, and the Y were determined. The pattern of asymmetry is simple in chromosomes 15, 16, and the Y but compound in 1 and possibly also 9. The pattern of compound lateral asymmetry is a stable heteromorphism inherited in a simple Mendelian way and is an efficient morphological discriminator between the members of the no. 1 chromosome pair.
