Question

males cannot mask the x - linked recessive trait because they only have 1 x chromosome. false true

Explanation:

In X - linked inheritance, males have one X and one Y chromosome. For an X - linked recessive trait, a male with the recessive allele on his single X chromosome will express the trait because there is no corresponding dominant allele on the Y chromosome (unlike females who have two X chromosomes and can have a dominant allele on one X to mask a recessive allele on the other). So the statement is true.

Answer:

True
