Multiple alleles help is producing variation.

The alleles in the ABO blood group system gives rise to __________ genotypes.

Which of the following is NOT an example of inter-genic gene interactions?

This type of inheritance pattern is called:

The inheritance pattern in which there is blending of traits in the phenotype is called?

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.

The hierarchy of dominance in the coat color of rabbit is:

Which of the following is true regarding coat color in rabbit?

A gene showing co-dominance has:

• Gene is the unit of heredity.
• Gene has two alleles.
• Two alleles can be same or different (like YY or Yy).

Which branch of biology focuses on the study of inheritance?

Phenotype means the ______________________ of an individual.

Semi-dominance or partial dominance is also known as:

Coat color in rabbit is an example of:

When two or more independent genes present on the same or different chromosomes interact to produce a new expression it is called:

Gene interactions occur as:

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.
