Importance of reducing chromosome sets

Witryna14 paź 2024 · Aneuploidy refers to extra homologous chromosome(s) being present within a chromosome set during a life span of their carriers or in one or a few subsequent generations (e.g., trisomy of a single chromosome leading to a 2n + 1 genome). Aneuploids may originate by several ways, with nondisjunction in meiosis or … Witryna9 kwi 2024 · Remembering that the purpose of meiosis is to reduce the sum of the genetic material by half, meiosis can equally divide an even number of chromosome sets, but not an odd number. Thus, polyploids with an odd number of chromosomes (e.g. triploids, 2n=3x) tend to be sterile, even if they are otherwise healthy.
