Which statement about inheritance is true? girls get most of their traits from their moms; boys get most of their traits from their dads. male offspring will always have an x-linked genetic disease if the mom is a carrier. fathers always determine the gender of the offspring in humans. males never have y chromosomes.

The correct answer is the third statement.

Explanation:

In humans, the males possess one X and one Y chromosome, while the females possess two X chromosomes. Thus, the female always donates X chromosome to the gamete. In any case, the female always generates a similar kind of gamete. While the male either pass X or the Y chromosome to the progeny.  

When the gamete with the X chromosome combines with the female gamete than the offspring would possess XX chromosomes and will be a female. On the other hand, when the gamete comprising the Y chromosome combines with the female gamete than the offspring would possess the XY chromosome and will be a male. Thus, it is the father who determines the gender of the offspring.  

The correct answer is Fathers always determine the gender of the offspring in humans.

Explanation:

Its C in Edge

genetic variation will increase because of a new habitat and food source.

explanation:

multiple allele inheritance is traits controlled by more than 2 alleles (ex: pigeons having 3 alleles of one gene govern their feather color).   so the answer is a.
