A feature associated with the Y-chromosome in human is

The feature associated with the Y-chromosome in humans is facial hair. The Y-chromosome contains genes that control the development of male characteristics, such as the growth of facial and body hair, deeper voice, and larger muscle mass. This is because the Y-chromosome is only present in males and is responsible for determining the male sex. Females do not have a Y-chromosome and therefore do not develop the same male physical characteristics, such as facial hair. So, if you see someone with a beard or mustache, it is likely that they have a Y-chromosome and are male.
