Answer 1

Answer:

you can understand from this

Answer 2

The following chart explains how parent with A and B blood group has child with O blood group.

Explanation:

• The parents with A and B blood group needs to be heterozygous to have child with O blood group.

• The parents with heterozygous blood group are actually having the genotype of AO and BO.

• So the two O from the genotype may actually come together to form a O child.

• The genotypes of these blood groups work as the inheritance of three alleles of same gene which are A, B and O.

• A and B are codominant where as the O blood group is recessive.

• So presence of any other allele with O makes the person have that blood group.

• While presence of both the alleles A and B makes the person have blood group AB.
