Homologous chromosomes are
chromosomes in a
biological cell that pair (
synapse) during
meiosis, or alternatively, non-identical chromosomes that contain information for the same biological features and contain the same
genes at the same
loci but possibly different genetic information, called
alleles, at those genes. For example, two chromosomes may have genes encoding eye color, but one may code for brown eyes, the other for blue.

A pair of chromosomes containing the same gene sequences, each derived from one parent.
Chromosomes that occur in pairs one having come from the male parent and the other from the female parent. They pair participate in crossing-over during meiosis. Homologous chromosomes contain the same array of genes but may contain different alleles at those loci.
