Lateral asymmetry in human constitutive heterochromatin: frequency and inheritance. 1978

R R Angell, and P A Jacobs

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.

UI	MeSH Term	Description	Entries
D008214	Lymphocytes	White blood cells formed in the body's lymphoid tissue. The nucleus is round or ovoid with coarse, irregularly clumped chromatin while the cytoplasm is typically pale blue with azurophilic (if any) granules. Most lymphocytes can be classified as either T or B (with subpopulations of each), or NATURAL KILLER CELLS.	Lymphoid Cells,Cell, Lymphoid,Cells, Lymphoid,Lymphocyte,Lymphoid Cell
D008297	Male		Males
D002877	Chromosomes, Human	Very long DNA molecules and associated proteins, HISTONES, and non-histone chromosomal proteins (CHROMOSOMAL PROTEINS, NON-HISTONE). Normally 46 chromosomes, including two sex chromosomes are found in the nucleus of human cells. They carry the hereditary information of the individual.

D005456	Fluorescent Dyes	Chemicals that emit light after excitation by light. The wave length of the emitted light is usually longer than that of the incident light. Fluorochromes are substances that cause fluorescence in other substances, i.e., dyes used to mark or label other compounds with fluorescent tags.
