haha sounds exactly like a problem in my bio class! Well first of all if you are a guy you only need one allele for the disease in order to have it, for women it would be two.This is why males are more prone to being born with color blindness. Well to figure this out you would need to make a punnet square, in this case that would a square divide up into four(looks like a window). I'll put a link of a diagram so you have an idea of what i'm talking about. Its kinda of done for you, only that you would have to change one of the alleles so that the individual is the healthy woman :) https://www.google.com/search?q=sickle+cell+punnett+square&safe=off&espv=2&biw=1280&bih=699&tbm=isch&imgil=ZFKBt4wUZesNGM%253A%253B2wnZGM41N5b6sM%253Bhttp%25253A%25252F%25252Fwww.picsofhealth2014.konecht.com%25252F127089-sickle-cell-anemia-punnett-square&source=iu&pf=m&fir=ZFKBt4wUZesNGM%253A%252C2wnZGM41N5b6sM%252C_&usg=__NOgFDxtik82j839j8MRXeZOliso%3D&ved=0CCcQyjc&ei=mbaNVMmbFJS1oQTItYLABA#facrc=_&imgdii=_&imgrc=ZFKBt4wUZesNGM%253A%3B2wnZGM41N5b6sM%3Bhttp%253A%252F%252Fwww.picsofhealth2014.konecht.com%252Fimages%252F64775-sickle-cell-anemia-punnett-square.jpg%3Bhttp%253A%252F%252Fwww.picsofhealth2014.konecht.com%252F127089-sickle-cell-anemia-punnett-square%3B700%3B475
