Sicle cell disease (SCD) is found in numerous populations whose ancestral homes are in the malaria belt of Africa and Asia. SCD

is an autosomal recessive disorder that results from homozygosity for a mutant β-globin gene allele. Data on one affected population indicates that approximately 8 in 100 newborn infants have SCD.Epidemiologic data on this population reveal that before the application of modern medical treatment, natural selection played a major role in shaping the frequencies of alleles. Heterozygous individuals have the highest relative fitness, and in comparison to heterozygotes, those who are βAβA have a relative fitness of 89 percent, but only about 43 percent of those with SCD survived to reproduce. What is the frequency of the wild-type (beta A) allele in this population? Express your answer using two decimal places. What is the frequency of the mutant (beta 8) allele in this population? Express your answer using two decimal places. What is the frequency of carriers of SCD in the population? Express your answer using two decimal places.

attashe74 [19]
The correct answer is the last option.

The first option (unable to cause climate change) is incorrect because these gases do effect the atmospheric temperatures by increasing them.
The second option is incorrect because while these gases do cause more water vapor to condense, they result in acid rain (not wetter climates).
