If a pair of homologous chromosomes fails to separate during meiosis I, select the choice that shows the chromosome number of the four resulting gametes with respect to the normal haploid number (n)? The Impact of Non-Separated Homologous Chromosomes in Meiosis I on Gametes’ Chromosome Number

The Effect of Homologous Non-Separated Chromosomes in Meiosis I On Gametes’ Chrosome 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). This is called non-disjunction and can occur due to a number of factors, including age, stress, or even environmental stress (Baker 2019, Moore 2020). As it can increase the likelihood of genetic abnormalities in offspring and chromosome anomalies, non-disjunction could have severe consequences for reproductive processes. It can also have negative effects on the well-being and health of offspring (Hegarty 2021; Kim 2019, 2019). It can cause infertility as the gametes may not be able to fertilize correctly (Lane 2016; Black 2021). To minimize health risk, you need to make sure that non-disjunction is not possible in meiosis 1. Cont….
