WebBy using punnet squares, even if everyone has the dominant allele from one parent, their children would have the possibility of having recessive alleles from both parents. It … WebAn organism can have a heterozygous at a particular locus but have a phenotype that looks like only one of the two alleles. This is because some alleles mask the appearance of others in a dominant/recessive pattern. A dominant allele produces its phenotype whether the organism is homozygous or heterozygous at that locus.

"WebDominant genes mask recessive genes. For example, brown eyes are the dominant gene for eye color, and blue eyes are recessive, so when the genes for brown and blue eyes are combined in offspring, there is a 75% chance that the offspring will have brown eyes. This is why the majority of people in the world have brown eyes. Problem " - Dominant and recessive genotypes
