Answer:
The correct options are:
A. Genes for the trait are present in both genders.
B. Growing a beard in males is an example of a sex-limited trait.
Explanation:
Sex- limited traits can be described as certain phenotypic traits which occur only in one of the genders of a species. The genes for the traits are present in both the males and females but they are not expressed in one of the gender. For example, the genes for beard are present in both males and females in humans. But the genes are expressed only in males. Females do not exhibit the expression of the genes for beard.
