Your friends Shania and Ricky are expecting a baby. Both Shania and Ricky are farsighted and have cheek dimples

Shania and Ricky have said that they hope that their baby won't need to wear glasses or have cheek dimples because they both hate their glasses and dimples. What can you tell them about genetic inheritance and the likelihood that they will get their wish?
What will be an ideal response?

A good answer will be similar to the following:
You can tell Shania and Ricky that both farsightedness and cheek dimples are dominant traits. That means that an individual who is heterozygous with one dominant allele and one recessive allele will still show the dominant trait. Given that both Shania and Ricky show the dominant traits, they both must have at least one allele for the dominant trait, so the likelihood that their baby will NOT have the dominant traits of farsightedness and cheek dimples is small.
