In Mendelian inheritance, several dominant genes from either parent usually present with the dominant form of the trait. Only those that received the recessive gene from both parents present with the recessive phenotype. This mode of inheritance implies that the child of two parents that display the "recessive" genotype should also display the "recessive" phenotype. Cheek dimples are a dominant phenotype. Attached earlobes are a recessive phenotype. Hitchhiker's thumbsIt also means the "recessive" phenotype may theoretically skip any number of generations, lying dormant in heterozygous individuals until they have children with someone who also has the recessive gene and both pass it on to their child.
