Eden Bradford · Answer 1

The correct option is d) None of the answer options is correct.

Explanation:

Option A is not correct because dominant traits are not only common to females. Males can also have these traits as common as females.

Option B is false because not all the offsprings can have the chance of being affected. For example, if the parent carrying the disease is heterozygous for the trait then not all offsprings will have the chance to have that disease.

Option C is false because not all dominant traits are common. Sometimes, a recessive trait is more common than the dominant trait.
