In peas, a gene controls flower color such that R= purple and r = white. In an isolated pea patch, there are 36 purple-flowering plants and 64 white- flowering plants. Assuming Hardy- Weinberg equilibrium, what is the value of q for this population? 0.36 0.64 0.75 0.80

In a species of lily, the color of the flower's petals is determined by a dominant purple allele (F) or recessive white allele (f). One hundred flowers in Hardy-Weinberg equilibrium were sampled, and only 15% of the population showed the phenotype of white. Which of the following numbers represents the calculated value of the recessive white allele frequency? 0.92 0.39 0.15 0.85

In pea plants, the color purple is dominant to the color white. A farmer with an isolated patch of pea plants counts 36 purple-flowering plants and 64 white-flowering plants. Assuming the patch is in Hardy-Weinberg equilibrium, what is the frequency of the white allele? 0.75 0.64 0.80 0.36

A founder population of interesting creatures is established, and the average probability of identity by descent is calculated for each subsequent generation as follows: Generation  F 1 0.05 2 0.0975 3 0.142625 4 0.2283625 a) What are the effective population sizes Ne for each Generation 1 through 4, relative to Generation 0 (the founder population)?  b) What is the effective population size of Generation 4 relative to Generation 3?  c) Is there any evidence for changes in population size after the founder event, and if so, at which generation did the size change in the number of breeding individuals occur?

In a population experiencing no selection, genetic drift, gene flow, mutation or non random mating, the allele frequencies at a locus where the R allele is dominant over the r allele, are as follows. R= 0.3 r=0.7 What is the expected heterozygosity of the population at that locus?

In aerobic respiration when is carbon dioxide produced? (a) when oxygen is used as the final electron acceptor in oxidative phosphorylation                     (b) glycolysis     (c) during substrate level phosphorylation     (d) Krebs cycle                               (e)  when hydrogen is pumped across the inner membrane of the mitochondria

You are studying a population of mice in a field that have black (genotype BB), dark brown, (Bb) or light brown (bb) fur.   In your population you have 49 black individuals, 274 dark brown and 206 light brown.   What is the frequency of the B allele in the population? (round to 2 decimal places)

In a species of lily, the color of the flower's petals is determined by a dominant purple allele (F) or recessive white allele (f). One hundred flowers in Hardy-Weinberg equilibrium were sampled, and only 15% of the population showed the phenotype of white. Which of the following numbers represents the calculated value of the recessive white allele frequency? 0.92 0.39 0.15 0.85

Below is a plot of genotype frequencies in a population. Assuming the population is in Hardy-Weinberg equilibrium, what is the probability that any given individual will have the m allele? 0.8 0.6 0.4 0.2 0.0 BB Bb bb

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. Another flock of geese is determined to have observed and expected numbers of individuals recorded in the table below.    Observed Expected DD 392 303.78 Dd 155 327.15 dd 172 88.08  Determine whether the flock is in Hardy-Weinberg equilibrium by performing a chi-square test. Show all of your work. Use the following table to determine the critical value to which you’ll compare your calculation of the chi-square statistic. Degrees of freedom P = 0.05 1 3.841 2 5.991 3 7.815
