Question

8) There are many antigens (i.e., proteins or glycoproteins) found on the surface of the red blood cell. The most relevant ones in blood transfusions are the ABO, Rh, and Kell antigens. The dominance pattems of several of the anmigenehoun below. ABO type 14 and codominant, i recessive Rh type R dominant to Rh MN type M and N codominant xae type xg(a dominant to xa- K type All of the blood types are autosomal except for XEe, which is X linked. K dominant to K In the below table, the phenotypes for several mother/daughter pairs are shown. Mother Daughter Possible fathers 2) A, M, K Rh , X 4) AB, N, K, Rh, X A. For each motherdaugher pair,chooe hepostble aeher F ay, fohpvn males. One father can be used multiple times. B. If mother and father 1 had a child, which daughter could be theirs?

Explanation / Answer

Please find the answers below:

Answer A: According to the information, the present crosses show both complete dominance and co-dominance for various phenotypes as demonstrated. Thus, the correct matches can be found as below:

Mother 1- Daughter -1- Father 1

Mother 2- Daughter -2- Father 3

Mother 3- Daughter -3- Father 2

Mother 4- Daughter -4- Father 4

Answer B: As per the given data and pairing rules in the information, if mother 1 and father 1 had a child, her phenotype would be similar to daugter 1 since all dominant and co-dominant groups match with this child only.
