What Happens When a Black Homozygous Cat Is Crossed With a White Cat?

Mendelian Genetics Example

A homozygous black cat has genotype BB. A white cat has genotype WW.

When crossed, all offspring inherit one allele from each parent, resulting in genotype BW.

Because black fur (B) is dominant over white (W), all offspring will have black fur while carrying the recessive white allele.
