Use the information provided to create a pedigree. Then answer the question at the end of each description. a. (Pretend*) the human ability to roll your tongue is dominant to not being able to roll your tongue (*it’s not really
that simple.). Draw a pedigree to show the inheritance of this trait, given the following family history:
Grandpa Snow is a tongue roller but Grandma Snow is not. They have four children, 2 sons and 2 daughters, who
are all rollers. Their last daughter, Judy, married John Flake. John’s parents are both rollers, but John’s two sisters
are non-rollers. John is a roller. John and Judy Snow-Flake have three children named Crystal Snow-Flake (nonroller), Delicate Snow-Flake (roller) and Jake Snow-Flake (roller).
Give the possible genotypes of each individual. Pedigree:
