In humans, the diploid number of chromosomes is 46, including the sex-determining X and Y chromosomes. Meiosis involves a single round of DNA replication, but two rounds of cell division; the products (spermatozoa or an oocyte) contain the haploid number of chromosomes (23 in humans). ...
Sexual reproduction begins with conjugation (i.e. the pairing of two cells of different mating types) and meiosis of the micronucleus in each member of the conjugating pair (Fig. 1A). Eventually, one haploid micronucleus from each cell is transferred to the other cell; the haploid nuclei then...
RobertResnikMD, inCreasy and Resnik's Maternal-Fetal Medicine: Principles and Practice, 2019 Errors in Mitosis Our discussion of meiosis was focused on cell division during gametogenesis. Duringmitosis, there is preservation of the diploid chromosome constitution (2n) during somatic cell division. The...
Lastly, chromosome segregation errors during gamete formation in meiosis are a primary cause of human birth defects and infertility. This review describes the consequences of mitotic and meiotic errors focusing on novel concepts and human health. Keywords: aneuploidy; polyploidy; microtubule; chromosome ...
