Final answer:

Sex-linked traits are inherited through alleles carried on the X and Y chromosomes, impacting males more frequently. Examples include red-green color blindness, hemophilia, and muscular dystrophy.


Explanation:

Alleles that are carried on X and Y chromosomes are always involved in the inheritance of sex-linked traits. In humans, traits like red-green color blindness, hemophilia, and muscular dystrophy are examples of X-linked traits. Females who are heterozygous carriers for these diseases can pass them to their offspring, resulting in a higher frequency of these traits in males compared to females.
