Unformatted text preview: A person who can taste Sodium Benzoate, thiourea or PTC is either homozygous dominant or heterozygous.

If one mutated gene (HbS) and one normal gene (HbA) are inherited, a person has abnormal hemoglobin. If two mutated genes (HbS) are inherited, then the person has sickle cell anemia. Johannesburg gets the anti-malarial funding since it is more susceptible to a Malarial pandemic. We have come to this conclusion based on the percentage of heterozygous individuals. Types of genetic drift: Genetic bottleneck and Founder effect. Heterozygous genotype cloaks recessive deleterious alleles and prevents them from being wiped out....
