Genotype BB Bb bb Phenotype Black Brown White Frequency 0.16 0.48 0.36 Fitness 0.72 0.82 1 What is the average fitness for color in this population of beetles? What is the frequency of black beetles after selection? What is the frequency of brown beetles after selection? What is the frequency of white beetles after selection?When a population is at Hardy-Weinberg equilibrium which one of the following is true? Group of answer choices Genotypic frequencies change generation after generation. One can calculate the recessive allele frequency directly from the number of homozygous recessive phenotypes seen. Individuals of the same genotype are most likely to mate. Allele frequencies change generation after generation.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.

Match each frequency with the correct value. Allele Frequency of b Allele frequency of B genotype frequency of BB Genotype frequency of Bb
- In a population of lynx, a census was taken in the spring and again a year later. In the spring, there were 400 baby lynx born, of which 300 had a normal speckled coat phenotype and 100 had a black phenotype. A year later, there were 200 speckled coat lynx and 50 black lynx that had survived to adulthood. Calculate the survivorship for each phenotype, and determine the relative fitnesses based on survivorship.

In an ideal pea plant population exhibiting Hardy–Weinberg equilibrium, 35 pea plants out of 100 have wrinkled seeds. Calculate the frequency of homozygous round pea plants in the population. Express your answer using two significant digits. AnswerIn a population that is in Hardy-Weinberg equilibrium, the frequency of the homozygous recessive genotype is 0.09. What is the frequency of individuals that are homozygous for the dominant allele?
- About 70 percent of all Caucasians can taste the chemical phenylthiocarbamide, and the remainder cannot. The ability to taste this chemical is determined by the dominant allele T, and the inability to taste is determined by the recessive allele t. If the population is assumed to be in Hardy-Weinberg equilibrium, what is the heterozygotes frequency in this population? a. 0.7 b. 0.4 c. 0.2 d. 0.5In a hypothetical bug population, color is determined by a single gene and black is dominant over white. The frequency of the black allele is 0.1. If this population is in Hardy-Weinberg Equilibrium, what percentage of the bugs would we expect to be white? Calculate the genotype frequencies of the 2nd generation is a hint.The frequency of allele A in a population is 0.8 and the frequency of allele a is 0.2. If the population mates randomly with respect to this locus, give all the possible matings among the genotypes at this locus and the expected proportion of each type of mating.
