Matching chromosomes are called homologous chromosomes.

Quick scoop

• Homologous chromosomes are pairs of chromosomes that have the same size, shape, and gene locations, but may carry different versions (alleles) of those genes.

• In humans, body cells have 23 pairs of homologous chromosomes (46 total), with one chromosome in each pair coming from the mother and the other from the father.

• During meiosis, homologous chromosomes pair up, exchange segments in crossing over, and then separate into different gametes, which increases genetic variation.
