WebIn this diagram the cell contains 3 pairs of homologous single chromosomes, a total of 6 chromosomes. Since the cell contains a total of 6 chromosomes, it has a chromosome number of 6. Chromosomes A & a represent one pair, B & b represent a second pair, and C & c represent a third pair. Chromosome segregation occurs at two separate stages during meiosis called anaphase I and anaphase II (see meiosis diagram). In a diploid cell there are two sets of homologous chromosomes of different parental origin (e.g. a paternal and a maternal set). During the phase of meiosis labeled “interphase s” in the meiosis diagram there is a round of DNA replication, so that each of the chromosomes initially present is now composed of two copies called chromatids.
