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. simulado professor warles matematicaWebFirst, a polar chromosome can remain unaligned through metaphase and anaphase and mis-segregate while still stuck at the polar region ( Figure 7, route 1).
