Answer:
b. Craig is right and doesn't have to pay child support.
Explanation:
ABO blood group is controlled by three alleles. IA and IB are codominant to each other and both are dominant over i allele. IAIA and IAi produce A blood group. IBIB and IBi produce B blood group. ii produces O blood group.
Susan's son has O blood group so his genotype must be ii. He got one "i" allele from Susan and one "i" allele from his father. Craig's genotype is IAIA so there is no chance that he could have passed on "i" allele to Susan's son. Hence Craig is not his father and does not need to pay child support.
Answer:

Answer:
The evolution of a species is driven by many evolutionary mechanisms two of which are: natural selection and the genetic drift.
The natural selection selects the species or the alleles which increase the reproductive success of the species in a given environment whereas the genetic drift cause evolution by randomly selecting the alleles based on the sampling error. The genetic drift selects the alleles or species by chance and not on the beneficial and harmful basis.
In the given question, If natural selection favours the one trait of the species on the basis if it provides fitness then it could result in a genetic drift of alleles of another trait as it is purely based on the chance.
