Mr. Mazer has three biological (blood-related) sisters: Janice, Kathy, and Jenai. Mr. Mazer has anemia. His identical twins sisters, Janice and Kathy, are both carriers of anemia. The youngest sibling, Jenai, is also a carrier for this trait. Mr. Mazer’s parents, Carmela and David, now deceased, were both carriers of anemia.
One sunny day in June, Mr. Mazer met his future wife, Marilyn, who was a carrier for this trait. Eventually, they had two daughters: Sarah (a carrier) and a beautiful, smart, talented, younger daughter Becky, who has anemia. When Janice married Ken (who carried anemia), they produced Zach who was a carrier. Kathy and her husband Keith produced three offspring: Danielle, Lauren, and Michael. All three of these offspring have anemia. When Jenai married Billy (who does not have anemia), they produced four children: Krystal, Michael, Taylor, and Joshua. The three boys are all identical triplets who do not have anemia, unlike their sister Krystal who is a carrier.
