Genetic variation is the variation in the DNA sequence in the genome of an organisms. Organisms of a species have similar characteristics but they are not identical due to genetic variation. Genetic variation is important in the survival and the adaptability of a given species of organism. Therefore, in this case lack of genetic variation necessary to adapt to change in the environment will lead to extinction of the fish species that lacks the variation.
Answer:
Woman's genotype is AO
Man's genotype is BO
Explanation:
For a woman with blood group A and a man with blood group B to give birth to a child with blood group O. Their genotypes will be:
Woman's genotype is AO
Man's genotype is BO
The can have a child with blood group A, B, AB and O
1/4 will have type AB blood group;
1/4 will have AO, which is type A blood group;
1/4 will have BO, which is type B blood group;
1/4 will have OO, which is type O blood group
