population of mice in Northern Iowa has two alleles for coat color, B and b. The population has 980 BB, 840 Bb, and 180 bb individuals. What are the genotype frequencies in this population

In squirrels, the gray allele (G) is dominant to the brown allele (g) at the coat color locus. A population of 153 squirrels in Pullen Park was scored for the coat color locus. The frequency of the gray allele was found to be 0.81. Due to construction at NC State, 57 NC State squirrels migrated to Pullen Park. The frequency of the gray allele in the NC State squirrels was 0.27. The squirrels mated randomly to form a progeny generation at Pullen Park. Assuming that no further migration occurred and that all other conditions for Hardy-Weinberg equilibrium were met, what is the frequency of the gray allele in the progeny generation at Pullen Park? Round your answer properly to 4 decimal digits. Answer:

Sickle-cell anemia is a recessive disease that afflicts approximately 1 in 12 African Americans, meaning that the frequency of ss homozygotes is 0.09. Assuming the African American population is in Hardy-Weinberg equilibrium, what is the frequency of Ss carriers in this population?

A population of North American Beavers (Castor Canadensis) contains 100 individuals. Beavers in this population show one of two phenotypes for fur color: red (R) or brown (r). 94% of individuals in this population have brown fur. List the genotypes below and give the frequency for each genotype.   Describe at least 3 scenarios in which the genotype frequencies could change.

The Rh factor is an antigen expressed on red blood cells and is controlled by a single gene. The dominant allele RH causes a person to be Rh, positive, and the recessive allele is represented as rh. Assume that a population is in Hardy-Weinberg equilibrium and 16 individuals out of 100 are Rh negative. What are the allele frequencies of RH and rh in this population? A. The allele frequency of RH is 0.80 and the allele frequency of rh is 0.20 B. The allele frequency of RH is 0.84 and the allele frequency of rh is 0.16 C. The allele frequency of RH is 0.50 and the allele frequency of rh is 0.50 D. The allele frequency of RH is 0.60 and the allele frequency of rh is 0.40

Human blood type is determined by three alleles, IA, IB, and IO. The alleles IA and IB are co-dominant to each other, and both are dominant to IO. These alleles combine to produce four phenotypes: type A, type B, type AB, and type O. Within a large, randomly mating population (540,000 individuals), the frequencies for the blood type alleles are 0.3 for the IA allele, 0.6 for the IO allele, and 0.1 for the IB allele. Calculate the expected numbers of people in the population having each of the blood types A, B, AB, and O. A. A = 48,600 people B = 5,400 people AB = 32,400 people O = 194,400 people   B. A = 243,000 people B = 5,400 people AB = 32,400 people O = 194,400 people   C. A = 162,000 people B = 54,000 people AB = 3,240 people O = 324,000 people   D. A = 194,400 people B = 64,800 people AB = 32,400 people O = 194,400 people   E. A = 243,000 people B = 70,200 people AB = 32,400 people O = 194,400 people

You sample a population of 189 mule deer for ear length alleles and find that 32% have AA, 42% have AB, and 26% have BB. If the HWE expected frequencies are AA=28%, AB=50%, and BB=22%, is this locus in HWE?

The color distribution for a specific population of snakes is 160 blue, 50 turquoise, and 40 green. The allele for the color blue is represented by B", whereas the allele for the color green is represented by BC. Both alleles demonstrate incomplete dominance. What are the genotype frequencies in the population? Calculate to at least two decimal places. BBBB : BBBG : BGBG. What is the allele frequency of B5 in this population? Calculate to at least two decimal places. allele frequency of BB:

In smurfs, blue tails and red tails are codominant to white tails (this is similar to blood type in humans). In a population of 200 smurfs, 6 have white tails, 93 have blue tails, 51 have red tails, and 50 have purple tails. Papa smurf has learned that the frequency of the blue tail allele is 0.53. Is this population in Hardy-Weinberg Equilibrium? Be sure to do a Chi-square test and show your work.

In a population, the dominant phenotype of a certain trait occurs 91% of the time. What is the frequency of the dominant allele?
