Person having genotype I^(A) I^(B) would...

Person having genotype `I^(A) I^(B)` would show the blood group as AB. Thus is because of

A

pleiotropy

B

co-dominance.

C

segregation

D

incomplete dominance

Text Solution

Verified by Experts

The correct Answer is:
B
ABO blood grouping in humans is an example of co-dominance. ABO blood groups are controlled by gene I. Gene I has three alleles `I^(A),I^(B),andI^(i)`. When `I^(A)andI^(B)` are present together, both express equally and produce the surface antigens A and B, whereas I is the recessive allele and does not produce any antigen. Pleiotropy referred the genetic effect of a single gene on multiple phenotypic traits. Incomplete dominance does not completely dominate another allele Segregation is the separation of allele during the process of gametogenesis. This is the basis of reappearance of recessive character in `F_(2)` generation.
