Answer:
- The blood group of the father must be B.
- The genotype of blood group would be .
- The Rh factor of the father can either be positive or negative.
- Thus, the genotype of Rh factor of father would be either Rr or rr.
Rh factor:
The phenotype of the mother Rh factor is positive. Thus, she can have Rr or RR as her genotype as positive is a dominant trait.
If the genotype of the mother is RR then all the offspring would be positive for Rh factor. However, one of the offspring is Rh negative, that means the mother must be heterozygous that is, Rr.
The genotype of the father can either be Rr or rr in order to produce offspring with positive as well as negative Rh.
Blood group:
The blood group of the mother is A. Thus, the genotype can either be or .
However, the blood groups of the children are O+ and B+.
Thus, the genotype of the mother must be heterozygous that is .
The blood group of the father must be B with genotype in order to produce offspring with blood group O and B.
The answer is commensalism

Answer:
<em>The correct options are :</em>
<em>A) The biodiversity will decrease because there are fewer species on the newly formed island.
</em>
<em>D) The species on the island will likely have lower genetic diversity than the species on the mainland.</em>
Explanation:
When a larger population is broken down and a smaller population is formed, the genetic diversity in the smaller population will be lower as it has fewer species. As a result, options for genetic variations will be lesser. Hence, the landmass which drifted away will have lower biodiversity than the mainland. There will be more number of species on the mainland hence the genetic diversity will be more there.

Explanation:
Answer:
D. predator population will decrease
Explanation:
If the population of prey species decreases then the competition between the predator population will increase and natural selection will act on them. So nature will select those individuals among predators who are more fit and adapted and less fit individuals will die.
So a few year after the predator population will decrease as there are not enough prey to support the large population of predators which was present when prey were abundant. Therefore the correct answer is D.
