WebSep 23, 2024 · The chromosomes in a homologous pair each have the same genes in the same order, but there may be variation between them, resulting in different alleles. Some of the variants in these alleles might have functional implications while others will not. During meiosis, homologous chromosomes line up and recombination occurs between them.
