C bb-montgomerycollege.blackboard.com. 4) Alisha has blood type B. Her mother has blood type O. Alisha marries Jared, who has blood type AB What is Alisha's genotype? What is Jared's genotype? Using a Punnett square, determine the probability of the couple having a child with the a. b. c. following: blood type B? blood type O? blood type AB? blood type A?

Answer 1

Answer

4)

A) Alisha's mother has blood group O hence her mother's genotype must be OO.

And Alish has blood group B so her genotype may be BB or BO.

As her mother is having two OO allele. She must jave inherited one O allele from her mother.

Hence Alisha's genotype must be 'BO'

B) Jared's blood group is AB hence his genotype is 'AB'

C)

Cross between

BO x AB

Punnett Square

	B	O
A	AB	AO
B	BB	BO

D) Daniels blood group is O hence his genotype must be 'OO'

E) Daniel and Alisha

OO x AB

	A	B
O	AO	BO
O	AO	BO

Hence

50% will be AO with blood group A

And 50% will be BO with blood group be.

Hence there will be 0 % chance of having child with blood group O
