Tollowing is FALSE A If a genetic disease reduces fertility and the allele that causes the disease offers no other advantage the allele will likely eventually disappear due to natural selection B Natural selection does not favor individuals who are homozygous for the sickle cell allele because these individuals typically die before they are old enough to reproduce OC Individuals who are heterozygous HbA HbS are protected from malaria and this is why sickle cell disease persists in wetter mosquito prone regions in Africa OD In regions where malaria does not occur individuals who are heterozygous HbA HbS have a fitness advantage over those who are homozygous for the normal hemoglobin allele H Reset Selection Question 2 of 8 1 Points FTER malaria is cured the frequency of the HbS allele should decrease in regions with lots of mosquitoes because A People will no longer die from sickle cell disease in these regions OB Having one copy of the HbS allele will no longer be advantageous in these regions OC Natural selection will no longer act on the HbS allele at all in these regions otic diseases eventually disappear
