The Mystery of Green Canaries

What kind of inheritance is demonstrated in the scenario of a bright yellow female canary mating with a dark blue male canary and producing green offspring?

a. Complete Dominance

b. Incomplete Dominance (Correct Answer)

c. Co-Dominance

Answer:

The scenario of a bright yellow female canary and a dark blue male canary producing green offspring is an example of incomplete dominance inheritance.

Explanation:

The situation described, where a bright yellow female canary and a dark blue male canary mate, resulting in green offspring, is an example of incomplete dominance inheritance. In incomplete dominance, the offspring's phenotype is a blend of the parents' traits. In this case, neither the yellow nor the blue gene is dominant, so the offspring inherits a blend of these traits resulting in a green color.

Just like in Mendel's experiments on inheritance patterns, where he crossed plants true-breeding for violet flower color with plants true-breeding for white flower color and got all violet flowers, the phenomena of inheritance can result in varied outcomes based on the genetic dominance patterns. However, in Mendel's experiment, one color was dominant while in the case of the canaries, neither color is dominant leading to a blend in the offspring.
