Answer:
IBi and IBIB
Step-by-step 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.
