How do sex linked disorders occur

X-linked recessive inheritance is a mode of inheritance in which a mutation in a gene on the X chromosome causes the phenotype to be expressed in males (who are necessarily hemizygous for the gene mutation because they have one X and one Y chromosome) and in females who are homozygous for the gene mutation, see ‎Sex differences in · ‎Examples · ‎Most common · ‎Less common disorders. For other X-linked recessive diseases for which we still do not know the For this reason, diseases such as DMD have continued to occur at relatively low. Because females have two copies of the X chromosome and males have only one X chromosome, X-linked recessive diseases are more common among males than females. However, X-linked recessive diseases can occur in both males and females.

  1. If the trait lowers the probability of fathering a child or causes the father to choose to only have children with women who aren't carriers so as not to create daughters who are carriers rather than expressers and then only if no genetic screening is used then women become even less likely to express the trait.

  2. It was once thought to be the "royal disease" found in the descendants of Queen Victoria. Most people have two sex chromosomes, one that is inherited from their mother and one that is inherited from their father. Because of that, it doesn't protect the male.

  3. The parents of an individual with an autosomal recessive condition each carry one copy of the mutated gene, but they typically do not show signs and symptoms of the condition.

  4. If a father is affected, his daughters will be carriers of hemophilia A and his sons will be unaffected. The second reason for female rarity is that women who express the mutation must have two X chromosomes that carry the trait and they necessarily got one from their father, who would have also expressed the trait because he only had one X chromosome in the first place. X and Y are sex chromosomes.

  5. An abnormal gene on the X chromosome from each parent would be required, since a female has two X chromosomes.
