Final answer:
The genotype IBi represents a heterozygous genotype, which is a type of genotype that has two different alleles for a particular gene. In the case of blood types, the alleles for blood type A (IA) and blood type B (IB) are codominant, so an individual with the genotype IBi will have the blood type AB, expressing both the A and B antigens on their red blood cells.
Step-by-step explanation:
The genotype IBi represents a heterozygous genotype. In genetics, when an individual has two different alleles for a particular gene, it is referred to as heterozygous. In the case of blood types, the alleles for blood type A (IA) and blood type B (IB) are codominant, meaning they are both expressed in the phenotype of a heterozygous individual. So an individual with the genotype IBi will have the blood type AB, expressing both the A and B antigens on their red blood cells.
