Please do these genetic problems:

1. Type B blood with a history of O and positive with a history of negative: I^BiPp

Cross that person with someone who is O negative: iipp

Treat this like a dihybrid cross. Two traits.

2. Can a person who is blood type A and a person who is Blood type B have an O offspring?

Solutions

Expert Solution

1. B blood group is dominant to O blood group. so B > i and Positive blood group is dominant to negative so P > p

P ---- BiPp X iipp

Gametes --- BP Bp iP ip ip

F1 - BiPp Bipp iiPp iipp

B+ B- O+ O-

2. It is possible to have a O blood group offspring from A and B blood group parents.

If Both A and B blood group parents are heterozygous containing one allele for O blood group, then there is possibility that two O alleles come together in an offspring which make him/ her O blood group. As O is recessive to A and B allele, Parents are not expressing O blood group, instead they re A and B blood group.

Q4. Human blood is grouped into four types: A, B, AB & O. Type O blood can be transfused to anyone (the universal donor) while people with Type AB blood can receive any blood type (the universal recipient). A country is recruiting soldiers but unsuccessful applicants accuse there exists discrimination on their blood type—too many Type A & B applicants are rejected while too many Type O & AB applicants are accepted. Use goodness-of-fit test, test whether the number of...
