describe how mitosis maintains a constant chromosome number
Report Abuse. Meiosis is the process where a constant number of chromosomes is maintained in a species. In normal somatic cell there are two sets of identical chromosomes.During meiosis the number of chromosomes from a gamete mother cell (2n), are halved and the gametes which are formed receive only one set of chromosomes(n).Then after fusion of these gametes during reproduction the zygote (2n) is formed. This zygote is again with normal 2 sets of chromosomes.uring meiosis the number of chromosomes from a gamete mother cell (2n), are halved and the gametes which are formed receive only one set of chromosomes(n).
