What is the end product of meiosis in terms of chromosome number and genetic content?

Meiosis ends with four haploid cells that each contain a single set of chromosomes and carry genetically diverse content. This happens because meiosis involves two rounds of division after one DNA replication. In the first division, homologous chromosomes pair and then segregate, reducing the chromosome number by half and allowing crossing over to occur—exchange of genetic material between homologs creates new combinations of alleles. In the second division, sister chromatids separate, producing four cells, each with a haploid set of chromosomes. The combination of crossing over and independent assortment of homologous pairs means the daughter cells are not genetically identical to each other or to the parent.
