Question

1.) Which statement below is not consistent with a population in Hardy-Weinberg equilibrium? A.) Genetic drift is occuring. B.) Random mating is occuring. C.) Population size is large. D.) Migration is not occuring. 2.) Sickel cell anemia is an autosomal recessive genetic disorder. Because individuals affected by sickle cell anemia have defective hemoglobin proteins, their blood cannot transport oxygen properly. There appears to be a relationship between the incidence of malaria and sickle cell anemia. Individuals with sickle cell anemia are carriers of the sickle cell allele have some resistance to malaria. Malaria is caused by the parasite Plasmodium and is transmitted between humans by mosquitoes.” If scientists are successful in significantly reducing or eliminating malaria, the best prediction for what will happen to the allele for sickel cell anemia in the population is that it will: A.)not be affected by the elimination by malaria. B.) increase as its selective advantage is increased. C.) by reduced as its selective advantage is decreased. D.) quickly disappear as its selective advantage is increased. 3.) “In a randomly mating populatuib of drosophila, 4% of the flies have black bodies (an autosomal recessive trait) and 96% have brown bodies. This population is assumed to be in Hardy-Weinberg equilibrium.” If a researcher samples 10 000 Drosophila from this population, the number of flies expected to be homozygous dominant for body colour is: A.) 400 B.) 3200 C.) 6400 D.) 9600
