In mink brown for color is dominant in silver blue for color if a heterozygous brown man is mated with a silver blooming and a offspring are produced how many would be expected to be silver blue

It is expected that 25% of the offspring are silver blue.

Explanation:

As was shown in the question above, in a population, the brown color is dominant, while the silver blue color is recessive. Thus, the brown color can be observed in dominant homozygous (AA) or heterozygous (Aa) organisms, since the dominant allele inhibits the expression of the recessive allele. However, the silvery blue color is only observed in homozygous recessive organisms (aa), since the recessive allele is only expressed in the presence of another recessive allele.

In the figure attached below, we can see that if a heterozygous brown organism (Aa) crosses with a silvery blue individual (aa), the offspring will be composed of 50% brown individuals (Aa) and 50% silvery blue individuals.

that is true   : ) hope this you
