Question

Three alleles control the ABO blood types. IA and IB are codominant genes, so the combination of IAIB produces the AB blood type. The third allele Iois recessive to the other two alleles. Indicate which of these parents could produce the given child.

1.A X AB produce B child.

2.A X O produce A child.

3.A X B produce O child.

4.A X AB produce O child.

5.A X AB produce B child.

6.B X B produce O child.

7.AB X AB produce A child.

Answer 1

All can produce the given child by focusing on their various genotypes in assumption except the parents with A x AB to produce an O child.

Step-by-step explanation:

A X AB produce B child: they can produce a child with B type if the individual with A type has the genotype AO.

A X O produce A child: they can produce a child with A type if the individual with A type has the either the genotype AO or AA.

A X B produce O child: they can produce a child with O type only if both individuals have the genotype AO and BO.

A X AB produce B child: they can produce a child with B type if the individual with A type has the genotype AO.

B X B produce O child: they can produce a child with O type only if both individuals have the genotype BO and BO.

AB X AB produce A child: it is possible for them to produce a child with blood type A.
