The cell has two sets of each chromosome; one of the pair is derived from the mother and the other from the father. The maternal and paternal chromosomes in a homologous pair have the same genes at the same loci, but possibly different alleles. A couple of homologous chromosomes, or homologs, are a set of one maternal and one paternal chromosomes that pair up with each other inside a cell during meiosis.
