Chromosomal non-disjunction occurs when chromosomes in anaphase I or chromatids in prophase II fail to separate, causing both copies to go to one daughter cell and none to the other.
A não-disjunção cromossómica ocorre quando os cromossomos na anáfase I ou cromátides na prófase II não se separam, resultando em ambas as cópias indo para uma célula filha e nenhuma para a outra.
