Answer:

If a father has type A blood and the mother has type AB blood, they cannot have a child with blood type O, although depending on the father's genotype, they may not have children with a B blood type either.

Explanation:

Blood type is determined by the presence or absence of surface antigens A and B, which is genetically determined and establishes the pattern of inheritance.

<u>Alleles that define the presence of antigens A and B are co-dominant, while the absence of antigens - as in blood type O - is a recessive trait</u>.

  • <em>Type A </em><em>contains antigen A and its genotype can be A|A or A|O. </em>
  • <em>Type B</em><em> contains the B antigen, whose genotype can be B|B or B|O. </em>
  • <em>Blood type AB</em><em> contains both antigens and a single genotypic expression A|B </em>
  • <em>Type O blood </em><em>lacks surface antigens, with genotype O|O.</em>

The father with blood type A can have two genotypes, A|A or A|O, which raises 2 possible scenarios:

1. <u>Father A|O with mother A|B </u>

Alleles       A         O

A              A|A      A|O

B              A|B      B|O

In this case there is no chance of having a child with blood type O, 50% chance of having children with blood type A, 25% B and 25% AB.

2. <u>Father A|A with mother A|B </u>

Alleles        A        A

A               A|A     A|A

B               A|B     A|B

50% chance of having a child with blood type A and 50% with blood type AB. In this case there is no chance of having children with blood type O or B.

Why is it easy for a virus to mutate?
drek231 [11]

Answer:

Viruses mutate very quickly The major reason that viruses evolve faster than say, mosquitoes or snakes or bed bugs, is because they multiply faster than other organisms. And that means every new individual is an opportunity for new mutations as they make a copy of their genetic material. Many of those mutations have no noticeable effect.
