Discover the Fascinating World of Genetics Through Chicken Breeding

What type of inheritance is demonstrated when a white hen is crossed with a black rooster producing erminette-color offspring?

A. incomplete dominance
B. polygenic inheritance
C. codominance
D. multiple alleles

Answer:

B. codominance

Genetics is a captivating field that involves the study of inherited characteristics and traits. In the case of breeding a white hen with a black rooster resulting in erminette-color offspring, the inheritance pattern displayed is codominance.

When two different alleles are both expressed in a heterozygote, with neither being dominant or recessive, it is known as codominance. In this scenario, the black and white alleles are both expressed, leading to the unique erminette color in the offspring.

This phenomenon showcases the fascinating complexity of genetics and how different traits can interplay to produce diverse outcomes. By understanding concepts like codominance, we gain insight into the intricate mechanisms at work in the world of genetics.
