Question

Quincy has type B blood.

Answer 1

Answer:

IBi and IBIB

Explanation:

Blood group in humans is determined by a single gene with three alleles (iA, iB and i). Alleles iA and iB are both dominant over i. This means that i allele will only be expressed in a homozygous state.

In the ABO blood group system, individuals will possess the following blood types when they possess the following genotypes:

Type A- iAiA or iAi

Type B- iBiB or iBi

Type O- ii

Alleles iA and iB are codominant, this means that they both phenotypically express themselves when combined as neither is dominant or recessive to the other. Hence, in an heterozygous state;

iAiB, the blood type of the individual will be Type AB.

Following this, Quincy with a type B blood will possess an allelic combination of iBiB (homozygous) or iBi (heterozygous) in her genotype.
