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. These copies have the same
genes in the same
loci where they provide points along each chromosome which enable a pair of chromosomes to align correctly with each other before separating during meiosis. This is the basis for
Mendelian inheritance which characterizes inheritance patterns of genetic material from an
organism to its offspring parent developmental cell at the given time and area.
