Chapter 7.2, Problem 7.49E

(a)

To determine

To Explain: that their next child could receive.

Explanation of Solution

Given:

Alleles inherited	Blood Type	Alleles inherited	Blood Type
A and A	A	B and B	B
A and B	AB	B and O	B
A and O	A	O and O	O

If both have researcher A and B blood groups, then their child could inherit researchers

A and A, A and B (which is the same as B and A), B and B blood groups.

(b)

To determine

To Explain: the possible blood types that this child could have, along with the probability for each blood type.

Explanation of Solution

Given:

Alleles inherited	Blood Type	Alleles inherited	Blood Type
A and A	A	B and B	B
A and B	AB	B and O	B
A and O	A	O and O	O

The respective blood types are then

A, AB, B

With AB twice more likely than A and B

Therefore it will be obtain blood type A 25%, AB 50% and B 25%
