The presence of a beard on some goats is determined by an autosomal gene that is dominant in males and recessive in females. Heterozygous males are bearded, while heterozygous females are beardless. What type of inheritance is exhibited by this trait?

Explanation:

Some autosomal genes may affect the phenotypes of individuals of one sex more than individuals of the other but they play no part in the development of being a male or being a female. this type of gene is thus a sex influenced autosomal gene. The type of inheritance exhibited by this trait in the male goat follows the autosomal dominant pattern of inheritance meaning the for the trait to be expressed, it has to be the dominant allele form on the X chromosome. In the females, this trait follows the autosomal recessive pattern of inheritance such that for a female goat to be bearded, the trait must be inherited as a homozygous recessive trait, while an heterozygous or a homozygous dominant female will be beardless.

yes? sounds right, but you didn’t ask a question.
