Detailed explanation-1: -The black and brown colors do not blend together: the black allele covers up the brown allele. This means that the black allele is dominant over the brown allele. Remember that dominant alleles cover up recessive alleles. If there is one dominant allele present, the dog will appear black.
Detailed explanation-2: -Since black fur B is dominant, so both parents with genotype Bb will be having black furs.
Detailed explanation-3: -At the end of the process the genotypic ratio is 1 (BB) : 2(Bb) : 1(bb). The phenotypic ratio will be 3 (Black fur) : 1 (brown fur).
Detailed explanation-4: -The gene for black fur (B) is dominant over the gene for white fur (b) in mice. A homozygous dominant female and a heterozygous male produce 200 offspring during their lifetime.
