Quizplus · Accepted Answer

Males are more likely than females to be affected by X-linked disorders.Females express the X-linked disease only in the rare instance in which both X chromosomes carry the defective gene.Males,however,do not have the safety margin of two X chromosomes and express the disease if their one and only X chromosome is abnormal.Males and females are equally affected by autosomal-dominant and autosomal-recessive disorders.Chromosomal nondisjunction means that paired homologous chromosomes fail to separate normally during either the first or second meiotic division,resulting in germ cells that have an abnormal number of chromosomes.This can occur in both males and females equally.
