Question

What are the similarities of incomplete dominance and codominance?

Answer 1

Incomplete dominance:

1. When the phenotypes of the two parents blend together to create a new phenotype for their offspring, it is called incomplete dominance.
2. An example is a pink flower that is produced from red and white flowers.

Codominance:

1. When the two-parent phenotypes are expressed together in the offspring, it is called codominance.
2. Examples are flowers with two different color petals and spotted cows.

Similarity:

The similarities between codominance and incomplete dominance are listed below:

1. Both codominance and incomplete dominance are dominant in nature.
2. Mendelian inheritance laws cannot explain the patterns of inheritance.
3. An allelic or intragenic gene interaction causes codominance and incomplete dominance.
