- In a particular species of flower, C1 codes for red flowers, C2 codes for white, with the heterozygous individuals being pink. A. In the frequency of pink individuals in the population was .7126, would you be able to estimate the frequencies of the individuals alleles in the population? Why or why not? B. If the frequency of red individuals in the population was .329, what would the estimated frequency of pink and white individuals be in the same population?Calculate all the frequencies and summarize them in the attached table. Then use the data to answer the questions below: Which of the following best describes the change in kdr genotype frequencies over time in A. gambiae? Choice 1 of 4:From pre-2006 to post-2006, the frequency of the r/r genotype increased slightly while the frequencies of +/+ and +/r genotypes decreased dramatically. Choice 2 of 4:From pre-2006 to post-2006, the frequency of the r/r genotype increased dramatically while the frequencies of +/+ and +/r genotypes decreased dramatically.

- Among a particular population of 100 plants, red flowers are dominant and yellow flowers are recessive. F is the dominant allele and f is the recessive allele. 40 plants are homozygous dominant • 44 plants are heterozygous 16 plants are homozygous recessive Use the Hardy-Weinberg equation to calculate the equilibrium frequencies of each genotypeCalculate selection for the following scenario. In a population of prairie dogs living on a prairie, prairie dogs with genotype aa have 8 offspring per year on average, those with genotype Aa have 4 offspring per year on average, and those with genotype AA have 3 offspring per year on average. Round selection to the nearest hundredth, report selection as a value ranging from "0.00" to "1.00" Selection on genotype Aa: Selection on genotype AA: Selection on genotype aa: Which genotype has the highest fitness? Fill in the blank with homozygous dominant, heterozygous, or homozygous recessiveIn tomatoes, red fruit (R) is dominant over yellow fruit (r). In a tomato plant population exhibiting Hardy–Weinberg equilibrium, if allele r has a frequency of 0.66, what percentage of the population is homozygous dominant for this trait? Express your answer using three significant digits. Answer%
- Imagine a population 528 individual plants. In this population, 4 % of the plants produce red flowers, and 9 % produce pink flowers. The remaining plants produce white flowers. Flower colour is attributed to a single locus with two alleles. Red flowers are produced by plants that are homozygote for the R allele. White flowers are produced by plants that are homozygote for the W allele. Heterozygotes (RW) produce pink flowers. What is the expected (under Hardy-Weinberg equilibrium) number plants producing pink flowers in this population? Round your answer to the closest full number.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.If there are 12 rock pocket mice with dark fur and 4 with light-colored fur in a population, what is the value of q? Remember that light-colored fur is recessive. If the frequency of p in a population is 60% (0.6), what is the frequency of q? In a population of 1000 rock pocket mice, 360 have dark-colored fur. The others have light-colored fur. If the population is in Hardy-Weinberg equilibrium, what percentage of mice in the population are homozygous dominant dark-colored mice?
- . In pea plants, height is controlled by a Dominant Allele (T) for Tall Height and by a Recessive Allele (t) for Short Height. If 96% of a population of pea plants have the tall phenotype, calculate the frequencies of dominant allele (T) & recessive (t) alleles. Out of the 96%, what is the estimation of how many are homozygous dominant vs. heterozygous? What is the frequency of the recessive phenotype?Population and Quantitative Genetics. Assume the mean value for Trait A in Generation 0 is 0.5. Mean value for those individuals that reproduce in Generation 0 is 0.75. Selection differential, S is 0.25.
