A Study of the Effects of non-separated homologous Chromosomes on Gametes’ Chromosome number
A type of cell division that produces gametes for sexual reproduction, meiosis can be described as Meiosis. Homologous chromosomes are normally separated in this first meiotic divide, creating four haploid cells (n). If a homologous pair fails to seperate, however, it will result in abnormally high chromosome numbers (n+1). (Kurz and Hegarty 2016, 2021). Non-disjunction is a phenomenon known as disjunction. It can also be caused by age or environmental stress (Baker 2019; Moore 2020). The reproductive process can be affected by non-disjunction. It increases the chance of offspring suffering from chromosome abnormalities or genetic disorders. This can lead to a decrease in the overall health and well-being for the offspring. (Hegarty, 2021, Kim, 2019). It can cause infertility as the gametes may not be able to fertilize correctly (Lane 2016; Black 2021). To minimize health risks, you need to make sure that non-disjunction is not possible in meiosis 1.
