Answer

Answer:

Sex - linked traits may be passed from parent to offspring on either the X chromosome or the Y chromosome.

Brief Explanations:

Sex - linked traits are not always dominant. They can be recessive too. Also, they are not restricted to heterozygous allele pairs. Sex - linked traits are carried on sex chromosomes (X or Y). For example, color - blindness is an X - linked recessive trait. Traits can be passed on the Y chromosome as well (e.g., some Y - linked male - specific traits).
