Ss ; oo

ss ; Bo

ss ; oo

1). The possibility of type O blood = Ss; oo & ss; oo = 2/8 = ¼ = 25%

2). The possibility of type Bo blood and be a carrier for sickle cell anemia, but not exhibit symptoms = Ss; Bo = 1/8 = 12.5%

3). The possibility their child will have sickle cell anemia with type B blood = ss ; Bo = 1/8 = 12.5%
