Number of homologous pairs in meiosis
WebSomatic Cells body cells Homologous Chromosome Chromosomes that contain the same genes, but may have different alleles. One set of genes comes from the female, the other set comes form the male. Diploid meaning "two sets". A cell that contains two sets of genes that contains homologous chromosomes. haploid meaning "one set". WebImagine that there are two or three or even 30 pairs of homologous chromosomes. Each homolog pair making up the tetrad in Metaphase I separates in Anaphase I. One homolog from the pair heads to one pole and the other heads to the opposite pole. Each pair of homologs moves independently of all the other homolog pairs that are also separating.
