Definition:
One of the threadlike "packages" of genes and other DNA in the nucleus of a
cell. Different kinds of organisms have different numbers of chromosomes. Humans
have 23 pairs of chromosomes, 46 in all: 44 autosomes and two sex chromosomes.
Each parent contributes one chromosome to each pair, so children get half of
their chromosomes from their mothers and half from their fathers.
