Homologous chromosomes in a sentence

A pair of homologous chromosomes , or homologs , are a set of one maternal and one paternal chromosome that pair up with each other inside a cell during fertilization. Homologs have the same genes in the same loci , where they provide points along each chromosome that enable a pair of chromosomes to align correctly with each other before separating during meiosis. Chromosomes are linear arrangements of condensed deoxyribonucleic acid DNA and histone proteins, which form a complex called chromatin. One homologous chromosome is inherited from the organism's mother; the other is inherited from the organism's father.
