Question

Quizplus · Accepted Answer

Sex-linked disorders are typically caused by recessive diseased alleles found on the X chromosome. Since females have two X chromosomes, they are less likely to express the disorder if they have a dominant healthy allele on one of their X chromosomes. However, males only have one X chromosome, so if they inherit the diseased allele, they will express the disorder.
