A member asked:

What are the odds that two parents (both carriers of sickle cell) will have offspring with sickle cell?

A doctor has provided 1 answer

25 %: Normal hemoglobin AA Sickle hemoglobin SS Sickle carrier (AS) So if both parents are carriers, then each has a AS genotype. ( roughly half of their hemoglobin is sickle m but they have no symptoms) the gametes ( SPERM OR EGGES) CAN BE either S or A , 50% chance of having S or A these are the possible offsprings AA 25% (normal), AS, SA 50% (carriers) , SS sickle cell disease 25%
