Question

Oswald has been diagnosed with a rare disease known as hyperdoodlemia. he must draw constantly during class or he will fall asleep instantly. He meets Fran who can't draw at all and takes very good notes in class instead of doodling. they get married after college and have three children. One daughter is plagued with this drawing disorder. She wants to determine if she obtained this disease/trait from her mother's side of the family or her fathers. She does some research that determines that it is an autosomal dominant trait of a 5P.23 mutation. She takes hair samples from her grandparents on both sides to do genetic testing. Her grandparents didn't go to school so they don't know if they have hyperdoodlemia. Oswald's parents both have the 5P.23 mutation on one chromosome each. Friends father is heterozygous for the mutation while her mother doesn't have the mutation at all. Draw a pedigree from the scenario above.
