Verified
Females are less likely than males to show sex-linked disorders because females
A) have higher levels of estrogen.
B) do not inherit recessive genes.
C) have an additional X chromosome.
D) have higher levels of testosterone.
Sex-Linked Disorders
Genetic disorders that are determined by genes located on the sex chromosomes, often resulting in diseases that have different frequencies or manifestations between males and females.
X Chromosome
Is one of the two sex chromosomes, with females having two X chromosomes and males having one X and one Y chromosome, playing a crucial role in determining genetic traits.
Estrogen
A group of steroid hormones that play a crucial role in the development and regulation of the female reproductive system and secondary sexual characteristics.

Final Answer :
C
Explanation :
Females have two X chromosomes, so if they inherit a recessive gene for a disorder on one X chromosome, they may have a normal gene on the other X chromosome that can mask the effect of the recessive gene. Males, with only one X chromosome, do not have this potential backup, making them more likely to express X-linked disorders.
