The frequency of the A1 allele is p = 0.4, and that of the A2 allele is q = 0.6. The observed  genotype frequencies are as follows:  f(A1A1) = 0.25 f(A1A2) = 0.36 f(A2A2) = 0.39 Is there a Hardy-Weinberg equilibrium in the population?

Use the equation p2+2pq+q2+1.0 to solve the following problem. In a population of 100 squirrels there are 64 black ones, and the remaining are white. Black (B) is the dominant allele, and the white (b) is the recessive allele. If the population is in Hardy-Weinberg equilibrium, what is the frequency of the black squirrels that are heterozygous (BB) for their coat color.   A. 0.48   B. 0.16   C.0.40   D. 0.32   E.0.64

If a disease determined by autosomal recessive heredity occurs at a frequency of 0.04 in a population, what is the frequency of this disease allele in the population? Assume Hardy-Weinberg equilibrium and use Aand a to symbolize the dominant and recessive alleles, respectively. Show calculation.

You sample a population of 200 mice and find 140 Aa individuals, 50 AA individuals, and 10 aa individuals. What are the genotype frequencies for Aa, AA, and aa, respectively (the population may or may not be in HWE at this locus)? Group of answer choices Can’t answer without knowing the allele frequencies in the population 2pq, p squared, q squared (#Aa) (1), (#AA)(2), (#aa) (2) 0.7, 0.25, 0.05

A population consists of 300 individuals with the following genotypes: AA – 100                               Aa – 125                  aa – 75 a.       What are the values of p and q? b.       Is the population in Hardy-Weinberg equilibrium? Explain.

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

The frequency of individuals who express a recessive disease in a population is 16%. What variable in the Hardy Weinberg equations does the 16% refer to? Why?

What are the frequencies of allele D and d in a population that has individuals with the following genotypes? DD=81 Did=18 dd =1

In a population of locusts, the mean wing length is 47 mm, the selection gradient on wing length is β = 0.12/mm, the phenotypic variance for wing length is P = 3.6 mm2, and the heritability of wing length is h2 = 0.27. In addition, we know that the additive genetic covariance between wing and leg length is 0.60 mm2. What is the expected evolutionary change in mean leg length due to selection on both wings and legs? Repeat these calculations to predict what will happen to wing length as a result of the selection on both wings and legs. What do you predict the average wing and leg lengths will be in the next generation?

Consider the following three diagrams of a nerve cell membrane. They show resting potential, depolarization, and hyperpolarization. Figure out which one is which, then draw them in the order they occur in a cell that undergoes an action potential outside + Na* inside K* Na* Nat K Nat K Na potential: -80 mV outside + Na K* Na* inside Na+ K Nat Na* K+ potential: +30 mV outside Na Na Na Na* K+ inside K* Na* Kt potential: -70 mV
