Hint:
The Bernstein "Three allele model" is used to determine the genotype of an offspring.
The correct answer is: 6
- Blood groups explained by Landsteiner involved the presence or absence of antigens (A and B) in the individual.
- Three allele model involves inclusion of Rh factor along with A and B antigens.
- As a result, an offspring can obtain one out of the six various combinations of genotypes from the parents, which are as follows:.
ABO
A
B

Which of the following is NOT an example of intra-genic gene interactions?
- Example of epistasis is fur color. The fur color of an animal depends on two genes (E and B). B gene is responsible for color while E gene determines the level of expression of the B gene.

In case of co-dominance:
- A, B and O are alleles responsible for blood groups.
- Neither of the allele is completely dominant over other.
- Example: For a person with AB blood group, the expression of both A and B alleles occurs.
