Quizplus · Accepted Answer

X-linked recessive genes are located on the X chromosome, which is one of the two sex chromosomes. Males have one X chromosome and one Y chromosome, while females have two X chromosomes. Therefore, if a characteristic is controlled by an X-linked recessive gene, it will be more likely to appear in males because they only have one X chromosome and have a higher chance of inheriting the recessive gene. In contrast, females have two X chromosomes, so they would need to inherit two copies of the recessive gene to display the trait, which is less likely to occur.
