You are observing a grouse population in which two feathers
Matings with dark-feathered males: 13 Matings with bright-feathered males: 32 Propose a hypothesis to explain why females apparently prefer bright-feathered males. What selective advantage might there be in choosing a male with alleles that make it more susceptible to predation? What data would help test your hypothesis?

Based on the data shown in the graph, select the statements that describe what happens whenever one sex becomes rare or common.
When one sex becomes rare, parents producing that sex have higher fitness due to a higher probability of mating success in their offspring. The rare sex becomes more common.
When one sex becomes common, parents producing that sex have reduced fitness due to a lower probability of mating success in their offspring. The common sex becomes rarer.
When one sex becomes rare, the other sex becomes common due to random fluctuations in the production of male and female offspring. The fitness of the parents is not affected.
When one sex becomes either more rare or more common, parents produce an equal number of sons and daughters. The sex ratio returns to an equal number of males and females.
Geneticists claim that if gene and genotype frequencies are not already in HW equilibrium, then one generation of random mating will lead to HW equilibrium frequencies for both alleles and for genotypes. What other factors besides random mating are necessary in a population for HW equilibrium frequencies of alleles and genotypes to be present?

- How Can We Measure Allele Frequencies in Populations? In a population where the females have the allelic frequencies A = 0.35 and a = 0.65 and the frequencies for males are A = 0.1 and a = 0.9, how many generations will it take to reach HardyWeinberg equilibrium for both the allelic and the genotypic frequencies? Assume random mating and show the allelic and genotypic frequencies for each generation.arrow_forwardIn a population of 2000 ladybugs at equilibrium, there are 1120 ladybugs with eight spots (SS), 30 with six spots (Ss), and 850 with four spots (ss). If random mating were to occur within the ladybug population, with no mutations, gene flow, or natural selection taking place, what would you expect the frequency of q to be in the next generation?arrow_forwardIn a certain population of frogs, 120 are green, 60 are brownish-green, and 20 are brown. The allele for brown is denoted GB, and the allele for green is designated GG. These two alleles are incompletely dominant to each other. If this population were in Hardy-Weinberg equilibrium, how many brownish-green frogs would you expect to observe?arrow_forward
- For goldfish, solid orange coloring is dominant while orange with black spots is recessive. A total of 2500 goldfish were stocked in an outdoor pond, 2275 solid orange and 225 orange with black spots. Since the fish came from a protected, indoor, stable environment, you may assume the stocked population was in equilibrium. What are the and genotype frequencies in the original stocked population?arrow_forwardIn a population of cats, the phenotypic frequency of black cats is 91%, and the phenotypic frequency of white cats is 9%. Assuming that black (B) is dominant and white (b) is recessive, identify the appropriate frequency for each of the following for a population in Hardy-Weinberg equilibrium. Match each frequency with the correct value. Allele Frequency of b Allele frequency of B genotype frequency of BB Genotype frequency of Bbarrow_forwardIn a certain population of frogs, 120 are green, 60 are brownish green, and 20 are brown. The allele for brown is denoted GB, and the allele for green is designated GG. These two alleles are incompletely dominant to each other. If this population were in Hardy-Weinberg equilibrium, how many green frogs would you expect to observe? (Remember to multiply the expected frequency by the number of frogs in the population.)arrow_forward
- Blue is dominant to pink in Snorks and green tongues are dominant to white. Also, six claws is dominant to 5 claws on each hand. A male snork heterozygous for all three traits mates with a pink snork, heterozygous for green tongue with 5 claws on each hand. What is the probability that they will have a pink Snork with green tongue and six claws for an offspring? Select one: a. 3/8 b. 3/16 c. 1/8 d. 1/16arrow_forwardDiscuss examples of positive and negative assortative mating in natural populations, human populations, and agriculturally important species.arrow_forwardYou are studying a population of giraffes. In this population, one gene (G) controls spot color in giraffes, which shows incomplete dominance. Individuals with white spots are homozygous gg, individuals with brown spots are homozygous GG, and heterozygotes have orange spots (Gg). You observe 25 white-spotted giraffes, 15 orange-spotted giraffes, and 22 brown-spotted giraffes. Calculate the observed allele frequencies, using p for the frequency of allele G, and the expected number of giraffes of each phenotype assuming Hardy-Weinberg Equilibrium (do not do the entire chi-square calculation!). For frequencies, report four positions after the decimal. For expected numbers, report two positions after the decimal. p = q = Expected number of orange-spotted = Expected number of brown-spotted = Expected number of white-spotted =arrow_forward
- Normally, male red ducks only try to mate with females of their own species. A researcher swapped eggs between the nests of red ducks and blue ducks (a different species) and found that if male red ducks were raised by female blue ducks, later in life they only tried to mate with female red ducks. Which of the following inferences is supported by these results? Group of answer choices The mate preference of male red ducks is environmental. The mate preference of male red ducks is genetic. The mate preference of male red ducks is innate. The mate preference of male red ducks is learned.arrow_forwardIn a certain breeding population, it is known for certain that only 9.8% of the individuals are "true-breeding" for the dominant phenotype. What would be the predicted frequency of individuals that are "true-breeding" for the recessive phenotype?arrow_forwardA rabbit warren has 300 individuals. The coat colour of rabbits is expressed through incomplete dominance. The coat colour can be dark brown, light brown, or white.There are 81 dark brown rabbits, 150 light brown rabbits, and 69 white rabbits. Assume that all of the conditions are met for a population in Hardy–Weinberg equilibrium.What is the light brown genotype frequency, the white phenotype frequency, and the dark brown allele frequency? Select one: a. Genotype of Light Brown Rabbits Phenotype of White Rabbits Dark Brown Allele Frequency 0.27 0.48 0.52 b. Genotype of Light Brown Rabbits Phenotype of White Rabbits Dark Brown Allele Frequency 0.50 0.23 0.52 c. Genotype of Light Brown Rabbits Phenotype of White Rabbits Dark Brown Allele Frequency 0.27 0.23 0.77 d.
