Question

why do all offspring have brown fur? a) because the allele for brown fur color is dominant b) because the allele for black fur color is dominant c) the genes were not mixed well enough d) because the allele for brown fur color is recessive

In genetics, dominant alleles are expressed over recessive alleles. If all offspring have brown fur, it is likely because the allele for brown fur color is dominant. When a dominant allele is present, its trait is shown in the phenotype of the offspring.
