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

Options

A. pleitropy
B. codominance
C. segregation
D. incomplete dominance

Answer

B

Explanation

A B O blood grouping in humans is an example of codominance. A B O blood groups are controlled by gene I. Gane I has three alleles `I^(A), I^(B) and I^(oi. lA) and I^(B)` are the dominat alleles. When `I^(A) and I^(B)` are present together, boht express equally and produce the surface antigens A and B, whereas I is the recessive allele and does not produce and antigen.
Pleitropy referred the genetic effect of a single gane on multiple phenotpic traits. incomplete dominance is a genetic term in which does not completely dominate another allele.
Segregation is the separation of all.ele during the process of gametogenesis. This is basis of reappearance of recessive character is `F_(2)`-generation.
