If those two cells each contain one set of chromosomes, then the resulting cell contains two sets of chromosomes. Haploid cells contain one set of chromosomes. Cells containing two sets of chromosomes are called diploid. The number of sets of chromosomes in a cell is called its ploidy level.

It includes prophase II, prometaphase II, metaphase II, anaphase II, telophase II, and cytokinesis. The process results in the separation of sister chromatids, producing four genetically unique haploid cells due to random assortment and recombination during crossover.

Despite their differences, they can pair during meiosis through pseudo-autosomal regions, enabling crossover. These regions include genes like SHOX, which affects height and may cause health issues in conditions such as Turner syndrome. Both XY males and XX females have two copies of these genes, while chromosomal aneuploidies can cause anomalies in gene expression.

Key mechanisms are outlined, including strand invasion, formation of D-loops, and resolution of Holliday junctions. It also discusses the proteins involved and the different pathways like DSBR and SDSA.

This rare occurrence leads to inheritance of parental combinations of alleles, with no recombinant types detected in the gametes.
