You are a fancy rat breeder investigating different characters in fancy rats. You have two true breeding populations of rats. One population's fur color is all brown. The other population;'s fur color is all black. You breed members of the brown population to members of the black population to get an F1 generation. The F1 generation grows up, you find they are all brown. You breed members of the F1 generation to other members of the F1 generation to get an F2 generation. When the F2 generation grows up, ~75% if them are brown, and ~25% of them are black. Statistically significant numbers of rat pups were produced in each cross. 1.Give the phenotype ratio of the F1 generation 2.Give the genotype ratio of the F1 generation. Give the individual genotype(s) 3. Give the phenotype ratio of the F2 generation. 4. Give the genotype ratio of the F2 generation. Give the individual genotype(s)

Say you have a lab population of 1000 dragonflies that is in Hardy Weinberg equilibrium. Body color is determined by a single gene with 2 alleles. The white body color phenotype is due to the homozygous recessive phenotype. Out of the 1000 dragonflies, 250 are white. Heterozygous and homozygous dominant individuals are green. How many of the 1000 dragonflies are green? Group of answer choices 1000 500 0 250 750
Genes and inheritance have an impact on the lives of parents and their progeny, the F1 and F2 generations. Population genetics also deals with genetics, but in a different way. What is the definition of population genetics? How can the abundance of an allele be different in a population as compared with an individual of the population? (Hint: How can the phenotype of a population differ from that of an individual? Can a population have red flowers, pink flowers, and white flowers? Can one individual have all three types of flowers?)

You observe a population of Japanese 4’oclock plants. These plants can display red, pink or white flowers. Plants with red flowers are homozygous dominant (RR); plants with white flowers are homozygous recessive (rr) and plants with pink flowers are heterozygous (Rr). Based on the following data: 35 plants with red flowers; 25 plants with white flowers; 40 plants with pink flowers. Show all work A) Calculate genotype frequencies of RR; Rr and rr in the population. B) Calculate the allele frequencies of R and r in the population.
You work for the science division of an agribusiness that is trying to stay ahead of upcoming food trends. The company predicts that duck eggs are likely to become a popular fad soon, and you've been tasked with determining the feasibility of harnessing the power of natural selection to breed ducks to produce more consistently sized eggs. You go through the recent records for the company poultry farm to examine egg size for ducks and their female offspring. The mean egg size is 120 grams, with a variance of 480 grams2. You plot out the results with the mothers' average egg size on the x-axis and average daughters' egg size on the y-axis, and you calculate the slope of your linear regression between the two as 0.28.What is the narrow-sense heritability for egg size in this population?
Lets say there exists a gene in the United States that comes in two alleles, the dominant A and the recessive a. The allele frequency of the dominant allele is 60% and the allele frequency of the recessive allele is 40% The population in genotyped and its found in the United States there are 36% Homozygous Dominant folk, 48% Homozygous Recessive folk, and 16% Homozygous recessive folk. Do you think there is any fitness advantage to any of these genotypes? Why or why not? View keyboard shortcuts
Valyrians have alleles for gene A, controlling hair color. The dominant A (silver hair) and the recessive a (brown hair). In a population of 3600 individuals, 2000 have genotype AA, 1000 have genotype Aa, and 600 have genotype aa. a-What is the frequency of allele a?
A population of frogs consists of 1000 individuals of which 400 are red. Red is recessive to Green. What is the frequency of the dominant allele and the recessive allele in this population? What is the frequency of individuals with homozygous dominant phenotypes? Please answer and show all work, thank you!! :)
In a certain population of mice, a single gene controls fur color. There are two possible alleles: B, which leads to a black fur, and W, which leads to white fur. Individuals with the genotype BB will have a black fur, individuals with the genotype WW will have white fur, and individuals with the genotype BW will have gray fur. Scientists recorded the fur color of 1,000 mice from the population. They found that 200 mice have black fur, 400 have gray fur, and 400 have white fur. Ten years later, the measurements are repeated. Again, they recorded the fur color of 1,000 mice. They found that 400 have black fur, 400 have gray fur, and 200 have white fur. Part A: Show the Hardy-Weinberg calculations for the beginning and ending populations. Include the values for the equation as well as the p and q values. Show your work. Part B: Use the Hardy-Weinberg calculation to explain if this population is evolving or not. Then propose a hypothesis about the environment of these mice that would lead…
A meadow is home to a population of plants of a particular species. Among these individuals are 125 plants that have red flowers and 375 plants that have white flowers. The allele of the flower color gene that produces red flowers (R) is completely dominant over the white flower color allele (r). If a plant with red flower color is crossed with a plant that produces all white flowers, what is the probability that the offspring will include plants that have white flowers? Group of answer choices a. 50% chance b. 75% chance c. 0% chance d. 25% chance e. There is not enough information to say.
You are studying a population of 1000 skunks (which are diploid). You sample alleles at two genetic loci, A and B. The A gene has two alleles A and a, and B has two alleles B and b. The frequency of the A, a, B, b alleles are p, q, r, s respectively, so that p = 0.2, q = 0.8, r = 0.3, s = 0.7. 1) Calculate the expected genotype frequencies of all possible genotypes under Hardy-Weinberg equilibrium. 2) Calculate the expected haplotype frequencies of all possible haplotypes assuming the two loci are unliked.
