The offspring are black feathered because the black feather gene is dominant
An Erminette chicken is a chicken with a gene for black feathers and a gene for white feathers. Since the genes are co-dominant, the Erminette chicken has black and white feathers, rather than one or the other or grey.
An erminette chicken would carry both a black gene and a white gene. The erminette chicken represents the heterozygous phenotype.

Both alleles for feather color are dominant.
Black chickens like white chickens and white chickens like black chickens.
A silky black copper chicken.
This type of inheritance is known as incomplete dominance, where the heterozygous offspring show a blend of characteristics from both parents rather than expressing a dominant trait. In this case, the erminette color results from a mix of black and white feathers due to incomplete dominance of black over white.
This cross of a black chicken with a white chicken producing an all black and white speckled offspring is an inheritance known as co-dominant inheritance.
If a homozygous black guinea pig (BB) is crossed with a homozygous white guinea pig (bb), all offspring will inherit one black allele (B) from the black parent and one white allele (b) from the white parent, resulting in heterozygous offspring (Bb). Since black fur is dominant over white fur, all offspring will have black fur. Therefore, the probability of an offspring having black fur is 100%.

Both parents were heterozygous (Bb). The offspring would statistically be: BB, Bb, Bb, and bb. All but the bb offspring would be black and the bb would be brown.
