INFOGRAPHIC 11.8 HOW DOMINANT TRAITS ARE INHERITED
Some genetic conditions, such as Huntington disease, a degenerative neurological disease, and polydactyly, having more than five fingers or toes per limb, are caused by dominant alleles. Many common traits such as dark eyes and dimples are also determined by dominant alleles. In these cases, inheriting one copy of the dominant allele is sufficient to display the trait.
