Quizplus · Accepted Answer

Male fruit flies only have one X chromosome, so if they inherit a recessive X-linked trait, they will express it. This is not the case for females, who have two X chromosomes and may have a dominant gene on one of them that masks the recessive gene on the other X chromosome. The other choices are not correct as there is no evidence to support them in relation to X-linked traits in fruit flies.
