A researcher is creating pedigrees for a trait he suspects to be dominant in humans. What are some of the likely features of his
pedigrees for families with this trait? a. Only females will have this dominant trait.
b. All the offspring of a mating where one parent has the trait will themselves be affected.
c. The occurrence of mating between individuals with this trait will be high, as all dominant traits are common within any given population.
d. None of the answer options is correct.
<em>The correct option is d) None of the answer options is correct.</em>
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.
