    (1) How might I explain the genetic basis of a disorder that occurs with equal frequency among both sexes and that doesn't follow basic patterns of Mendel inheritance??????

    (2) Explain the idea of heterozygote superiority with respect to human genetic disorders.

    (3) In a rare form of colour blindness, a person cannot distinguish the colour blue. This abnormality, when it does occur, affects both males and females and in equal numbers. Explain this pattern of inheritance and compare it to that involved in red-green colour blindness. :?

    Hmmm....I think transfusion is useful in treating people with sickle cell because the transfusion replaces the bad blood containing sickle shaped erythrocytes that clump together and cause problems with good blood containing normal erythrocytes.

    Because the human erythrocytes do not have a nucleus, the erythrocytes one got from the transfusion die in about 1 month and gets replaced by the sickle erythrocytes produced by the body again. So another transfusion is required.

    it's more like that the blood of a normal person has anti sickle erythrocyte enzymes or any substance in it. That will stay in a little longer.

    Just speculating, but it's another option why to preform transfusions. The ery's are all a welcome byproduct i guess.

    i'm really NOT sure about it.. needs to be investigated i guess..
