About 35 out of every 100,000 children born in the US have PKU (autosomal recessive). Assuming an ideal population and random mating, what is the frequency of the PKU allele in the US?

Homework Answers
Frequency of Homozygous recessive pp = 35/100000 = 0.00035,
So the frequency of p allele = underroot of 0.00035 = 0.0187 or 0.019.
So the correct answer should be: Option C) 1.9%

Humans who are born homozygous for the recessive sickle cell allele die of sickle cell anemia,...
Humans who are born homozygous for the recessive sickle cell allele die of sickle cell anemia, while those who are heterozygous are resistant to malaria (see chapter 4 for more information on this balanced polymorphism). 4% of the population of the Congo are homozygous recessive for the sickle cell allele. What percentage of the population is resistant to malaria? Red hair is a result of a recessive mutation at the melanocortin 1 receptor (MC1R). As you learned, about 13% of the...

2) Tay-Sachs disease is an autosomal recessive neurological disorder that is fatal in infancy. Despite its invariably lethal effect, Tay-Sachs disease occurs at very high frequency in some Central and Eastern European (Ashkenazi) Jewish populations. In certain Ashkenazi populations, 1 in 1000 infants has Tay-Sachs disease. Population biologists believe the high frequency is a consequence of genetic bottlenecks caused by pogroms (genocide) that have reduced the population multiple times in the last several hundred years. a) In the population described,...

In a hypothetical population which is in Hardy Weinberg equilibrium, the frequency for a recessive allele is 30%. What percentage of the population would be expected to show the dominant trait in the next generation? Humans who are born homozygous for the recessive sickle cell allele die of sickle cell anemia, while those who are heterozygous are resistant to malaria (see chapter 4 for more information on this balanced polymorphism). 4% of the population of the Congo are homozygous recessive for...

Tay-Sachs disease is an autosomal recessive disorder. Among Ashkenazi Jews of central European ancestry about in 1/3600 children are born with Tay-Sachs disease. What is the frequency for being a carrier for Tay-Sachs in this population? A carrier does not show the trait but can pass it on to his/her offspring.

Canavan disease is an autosomal recessive disease that causes progressive damage to nerve cells in the brain. Symptoms such as mental retardation, loss of motor skills and abnormal muscle tone progress rapidly beginning in infancy. The disease is fatal with no cure, and death usually occurs before age 4. This disease is caused by mutations in the gene for aspartoacylase on chromosome 17. In the Ashkenazi Jewish population, 1 in 10,000 persons are born with the disease. Assuming that this...
The occurrence of the NN blood group genotype in the US population is 1 in 400,...
The occurrence of the NN blood group genotype in the US population is 1 in 400, consider NN as the homozygous recessive genotype in this population. You sample 1,000 individuals from a large population for the MN blood group, which can easily be measured since co-dominance is involved (i.e., you can detect the heterozygotes). They are typed accordingly: BLOOD TYPE GENOTYPE NUMBER OF INDIVIDUALS RESULTING FREQUENCY M MM 490 0.49 MN MN 420 0.42 N NN 90 0.09 Using the...

3. Sickle-cell disease is a genetic condition caused by an autosomal recessive allele which al- fects one in every 500 African American children born in the U.S. One in every ten African Americans is a carrier for the recessive allels. Although sickle cell disease is caused by a single human gene, it is expressed through many different effects throughout the body. The presence of a recessive sickle-cell allele in humans causes the red blood cells to produce abnormal hemoglobin protein...

Gene Frequencies We will let p designate the frequency (=proportion) of gene B in a population, and we will let q designate the frequency of gene b. Since these are the only two alleles for that characteristic, then p + q = 1. (When all possible outcome frequencies are added, the sum of their frequencies must equal one (certainty)]. Now let us assume that completely random mating and offspring survival occurs...
