Types Of Inheritance And Pedigrees
... The result is that females will have two copies of the sexlinked gene while males will only have one copy of this gene. If the gene is recessive, then males only need one such recessive gene to have a sex-linked trait rather than the customary two recessive genes for traits that are not sexlinked. ...
