In some chickens, the gene for feather color is controlled by codominance. The allele for black feathers is B and white feathers is W. The heterogenous genotype is known as erminette. Erminette chickens will look “spotted”.

In some varieties of chickens, the allele for black feathers is codominant with the allele for white feathers. A cross between a black chicken and a white chicken will result in chicken with both black and white feathers.

​​​What is genetics? Genetics is the scientific study of genes and heredity—of how certain qualities or traits are passed from parents to offspring as a result of changes in DNA sequence. A gene is a segment of DNA that contains instructions for building one or more molecules that help the body work.

Therefore, the chicken could either be black (BB) or black and white (BW). There's a 50% chance that the black and white parent will pass on the white (W) gene. As a result, the chance of having a black and white chicken from this mating is 50%.

heterozygous Alternatively, a genotype that has two different alleles, for example: Gg, is called heterozygous. It is important to note that only when an organism has a homozygous recessive genotype, will the recessive phenotype be expressed.

The genotype of offsprings will be BW. The color of feathers will be black and white as both alleles express in the phenotype and neiter of tese two alleles is able to dominate over the other. The feather color in chicken in question exhibits the phenomenon of incomplete dominance.
