False, the growth of an organism is the result of cells multiplying.
Answer:
A. 50% Type A, 50% Type B
Explanation:
To answer this we can draw a punnett square.
Since o if recessive, it can only be expressed if it is not masked by a dominant allele. Therefore the male with type O blood has the genotype oo. A and B are co-dominant, so the woman has genotype AB.
_ | A | B
o |Ao | Bo
o | Ao | Bo
Since A and B are dominant alleles, they will mask the o allele. Therefore genotype Ao will be a Type A phenotype, and genotype Bo will be a Type B phenotype.
Therefore, the phenotypic probabilities for this cross is 50% Type A, 50% Type B. Hence, the answer is A.

<span>Genetic drift is the variation in different genotypes in a small population due to certain events that produce a large change in population, such as organisms dying out. The result of this genetic drift is that large changes in allele frequencies can occur in a short time.</span>
the second one is the one i would choose. hope this helps!
