In humans, albinism is caused by loss-of-function mutations in genes involved in the synthesis of melanin, the dark pigment in skin. only people homozygous for a loss-of-function allele (genotype aa) have the albino phenotype. in americans of northern european ancestry, albino individuals are present at a frequency of about 1 in 10,000 (or 0.0001). assuming that genotypes are in hardy−weinberg equilibrium, what is the predicted frequency of caucasians in the united states who carry a single allele for albinism?

The frequency of carriers of the albino allele in the population is. If

To solve this problem, we need to consider the Hardy-Weinberg equation which is the following:

p^2 + 2pq + q^2 = 1

where:  p = frequency of the "A" allele

q = frequency of the "a" allele

In other words, p^2 refers to the frequency of the homozygous(dominant) genotype AA, q^2 represents the frequency of the homozygous(recessive) genotype aa, and 2pq represents the frequency of the heterozygous genotype.

In the problem, if q = 0.01, and p = 0.99, then the frequency of carriers is 2pq which then becomes 0.0099 x 2. Thus, the predicted frequency of Caucasians in the U.S. who carry a single albino allele is 0.0198.

false because ozone (o3) depletion does not cause global warming, but both of these environmental problems have a common cause: human activities that release pollutants into the atmosphere altering it.

global warming is caused primarily by putting too much carbon dioxide into the atmosphere when coal, oil, and natural gas are burned to generate electricity or to run our cars.
