kelsey34Participantif a sickle-cell anemia is a recessive disorder, and a woman does not have it, but her father does, then would it be expressed as Ss or ss for the woman?
Huntington’s disease is a dominant disorder. so if the woman’s child was hhSs (hh meaning that they didn’t carry Huntington’s disease), would the child carry sickle-cell anemia?
thanks!

it would be expressed as Ss b/c the father would have to be SS since its recessive and he would give a S. Since she doesn’t have it it would have to be Ss. She would not carry sickle cell. Huntingdon’s and Sickle cell are not linked traits. You’ll probably cover linked traits soon. In other words these two traits sort independantly and have no effect on one another

I mean the father would be ss but that would still not effect your answer b/c the geneotype would still be Ss (s from father and S from mother)
