Cystic fibrosis (CF) is a recessive autosomal disorder. In certain populations of Northern European descent, the number of people born with this disorder is about 1 in 2500. Assuming Hardy- Weinberg equilibrium for this trait: A. What are the frequencies for the normal and CF alleles? B. What are the genotype frequencies of homozygous normal, heterozygous, and homozygous affected individuals? C. Assuming random mating, what is the probability that two phenotypically unaffected heterozygous carriers will choose each other as mates?

For a gene existing in two alleles, what are the allele frequencies when the heterozygote frequency is at its maximum value, assuming Hardy-Weinberg equilibrium? What if there are three alleles?

From the pedigree shown here, answer the following questions with regard to individual VII-1. A. Who are the common ancestors of her parents? B. What is the inbreeding coefficient for this individual?

Two alleles have been found at the X-linked phosphoglucomutase gene (Pgm) in a Drosophila persimilispopulation in California. The frequency of the PgmAallele is 0.25, while the frequency of the PgmBalleleis 0.75. Assuming the population is at Hardy-Weinbergequilibrium, what are the expected genotype frequencies in males and females?

In fruit flies, long wings (L) are dominant over short wings (l). In a population of 45 fruit flies, 27 have LL genotypes, 13 have Ll genotypes,  and 5 have ll genotypes. Find the frequency of the following. Show all work and record your answer as a value between 0 and 1 rounded to two decimal places.a. long-winged fruit flies: b. short-winged fruit flies:

Answer the question, using the graphs attached.

In a human population at equilibrium, three genotypes are present in the following proportions:       A/A = 0.81, A/a = 0.18, a/a = 0.01.  Answer the following questions: What are the frequencies of gene A and gene a? What will their frequencies be in the next generation? What proportion of all marriages in this population is between heterozygotic parents?

There is a gene that causes people to have crumbly earwax. This gene is expressed as a complete dominant: Individuals who are homozygous dominants (CC) or heterozygous (Cc) have crumbly earwax. Homozygous recessives (cc) have gooey earwax. There are 100 people, 64 of whom have crumbly earwax. Assuming Hardy-Weinberg conditions, what is the frequency of the c allele on Paradise Island? Group of answer choices 0.80 This cannot be answered without more information. 0.60 0.36 None of the above.

Explain why you need both the multiplication and addition rules to calculate the probability that an MN offspring will be produced in a human population The multiplication rule gives the probability that a particular mating will occur and that mating will produce the target genotype, and the addition rule gives the total probability of each target genotype, because the matings that produce the target genotype are mutually exclusive. The multiplication rule gives the probability that a particular mating will occur, and the addition rule gives the probability that the mating will produce the target genotype. The addition rule gives the probability that a particular mating will occur and that mating will produce the target genotype, and the multiplication rule gives the total probability of each target genotype. The multiplication rule gives the probability that a particular mating will produce the target genotype, and the addition rule gives the probability of obtaining the particular…

Snow geese (Chen caerulescens) come in two color types, white “snows” and “blues” with dark bodies. A single gene controls coloration, where the dark (“blue”) allele (D) is dominant. A population of 30,012 geese includes 9236 dark individuals. Genetic testing reveals that 7636 of the 9236 dark individuals are heterozygous (Dd). According to the Hardy-Weinberg equilibrium, what is the expected frequency of genotype Dd? Group of answer choices A.) 0.492 B.) 0.181 C.) 0.297 D.) 0.453
