In humans, the allele for dimples (D) is dominant to the allele for no dimples (d). If
two people who are heterozygous for the trait have children, what are the
predicted phenotype ratios of their offspring? (Hint: Make a Punnett square on
scratch paper.)
All will have dimples
3 dimples : 1 no dimples
1 dimples ; 3 no dimples
2 dimples : 2 no dimples
