Question
X-linked recessive disorders can affect more human males than females because ______ always express the disorder when they inherit the recessive allele from ______.Multiple choice question.males; the fathermales; the motherfemales; the fatherfemales; the mother
Solution
The correct answer is "males; the mother". This is because males have one X and one Y chromosome, while females have two X chromosomes. In X-linked recessive disorders, a male who inherits the recessive allele from his mother will always express the disorder because he does not have a second X chromosome to potentially carry the dominant allele. On the other hand, a female would need to inherit the recessive allele from both parents to express the disorder, making it less common in females.
