WebA pair of homologous chromosomes, each consisting of a single chromatid in a daughter cell at the end of mitosis, has alleles from the father and from the mother, and counts as 2 chromosomes. This chromosome number stays the same after chromosome replication during S phase: each chromosome entering cell division now consists of a pair of sister … Web5. Some of these homologs have one or more chiasmata, an X shaped region where a genetic rearrangement has occurred. This formation occurs because of sister chromatid cohesion, where a gene that has been given to the homologous pair in synapsis is still bonded to the corresponding part on the sister chromatid of its former chromatid. 6.

WebA somatic (body) cell contains homologous pairs of chromosomes, whereas a gamete (sex cell) will only contain one from each pair. These cells are called diploid and haploid respectively.
