The inheritance of genetic traits from parents to children follows predictable rules. Knowing that each parent contributes genes equally to each child, what determines an inherited trait such as eye color? * A. Only the interaction between dominant genes.
B. Only the interaction between recessive genes.
C. The interaction between dominant and recessive genes.
D. The interaction between dominant and recessive genes does not determine inherited traits.

c is right answer.

The interaction between dominant and recessive genes

Explanation:

Eye colour and blood groups are both examples of dominant/recessive gene relationships.

Eye colour

The allele for brown eyes (B) is dominant over the allele for blue eyes (b). So, if you have one allele for brown eyes and one allele for blue eyes (Bb), your eyes will be brown. (This is also the case if you have two alleles for brown eyes, BB.) However, if both alleles are for the recessive trait (in this case, blue eyes, bb) you will inherit blue eyes.
