FoxP2, the gene is thought to be involved in language in humans. At prophase (I), four copies (one on each sister chromatid in a pair of homologous chromosomes) of the FoxP2 gene are present in a cell.

What are homologous chromosomes?

Homologous chromosomes are two DNA segments within a diploid organism that have the same gene, one from each parental source. Briefly, both parents contribute the complete genome. Each parent contributes the same 23 chromosomes encoding the same genes. So our cells have a total of 46 chromosomes in two copies. However, each homologous chromosome can provide different versions of each gene. Having two versions of each gene increases diversity, reduces the adverse effects of negative mutations, and generally stabilizes populations. Homologous chromosomes are pairs of chromosomes containing both maternal and paternal chromatids of the same length and gene location and connected by centromeres. Homologous chromosomes in the nuclei of gamete pairs in meiotic organisms. This event is important for driving genetic variation. Homologous pairs exchange genes through genetic recombination so that genetic diversity can be promoted.
