  1. A pair of chromosomes made up of two homologs. Homologous chromosomes have corresponding DNA sequences and come from separate parents; one homolog comes from the mother and the other comes from the father. Homologous chromosomes line up and synapse during meiosis.

2. chromosomes in different species that have retained most of the same genes during their evolution from a common ancestor.
