Solution: Suppose that Jess has mycotonic dystrophy and shows traits such as uncontrolled muscle activity. Jess's mother, Rose, is dystrophic, but her father is normal. Jess is married to Dave, and Dave is norm

Problem

Suppose that Jess has mycotonic dystrophy and shows traits such as uncontrolled muscle activity. Jess's mother, Rose, is dystrophic, but her father is normal. Jess is married to Dave, and Dave is normal. Jess and Dave have a daughter, Lisa, and two sons, Phil and Erik. Lisa and Phil are normal, but Erik is dystrophic. Jess's sister, Jill is normal. Jill's husband and their only child are also normal. Jess's brother, Pete is dystrophic, and has three children with Mary, who is normal. Pete and Mary have two daughters, Judy and Pat, as well as a son, Carl. Judy is normal, but Pat and Carl are dystrophic.

Label six of the pedigree symbols with the corresponding names of the individuals in Jess' family.

Solution

The pedigree structure uses squares for males and circles for females. The black shapes are the affected individuals for the defect/disorder. The given information in the problem can easily be followed to complete the pedigree.
