Hallo~~
Your question is related to genetics.
Have you ever done a Punnett Square? This question forces you to make one. If your cross a homozygous type A (AA) and homozygous type O (OO) you should get 100% AO. Understanding genetics, an AO gene means a type A blood. Therefore, it's 100% type A blood (AO).
The law of segregation is the Mendel’s laws or principles
explain that traits are passed from parents to offspring individually instead
of as pairs, groups or sets. So the correct option is option “C” as far as the
given question is concerned. This is a law or principle which states that
during the formation of gametes, two copies of each heredity factors separate
out so that the new offspring can get one factor of both the parents. This law
was the first law in this direction.
B Since protons and electrons have to be the same amount!
