WebThe two gametes (sperm and ovum) contain 23 chromosomes (n) each and when the sperm fertilizes the egg (ovum), the zygote now has a total of 46 chromosomes and becomes diploid (2n). This zygote then goes through many stages of the replication cycle to create more and more cells called somatic cells or body cells. WebFirst, a polar chromosome can remain unaligned through metaphase and anaphase and mis-segregate while still stuck at the polar region ( Figure 7, route 1). Interestingly, the frequencies of unaligned chromosomes in anaphase across different cell types are not known, although they are expected to be low [ 124, 178 ]. bitbucket git push authentication failedWebIn each round of division, cells go through four stages: prophase, metaphase, anaphase, and telophase.
