How Can We Measure Allele Frequencies in Populations? Drawing on your newly acquired understanding of the HardyWeinberg equilibrium law, point out why the following statement is erroneous: Because most of the people in Sweden have blond hair and blue eyes, the genes for blond hair and blue eyes must be dominant in that population.
How Can We Measure Allele Frequencies in Populations? The MN blood group is a single-gene, two-allele system in which each allele is codominant. Why are such codominant alleles ideal for studies of allele frequencies in a population?
You are a rabbit breeder, and you decide that you want rabbits with long fur. Thephenotypic variance of fur length is 4 cm2. The covariance of fur length between betweenfull sibs is 1 cm2. The mean fur length in the initial population is 3 cm. You choose to breedthe top 1/3 of the population with the longest fur, and their mean fur length is 5 cm. Assumethat the covariance between sibs is due to only additive genetic variance.a) What is the narrow sense heritability (h^2 ) of fur length?b) What do you expect the mean fur length to be in the progeny of rabbits you breed?c) How many generations of this selection regime will it take for the mean fur length of thepopulation to be 10 cm? (Assume heritability and additive genetic variance remainunchanged throughout this process.)
In a population of snails, a locus affecting shell color has 2 alleles. The D allele produces a dark shell, while the d allele produces a white shell. Heterozygote individuals (Dd) have a yellowish shell. In a sample of 150 snails, 47 snails have a white shell, and 12 have a yellow shell. What is the frequency of the D allele? Round your answer to the second decimal place (0.00)
In 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. What is the frequency of genotype GGGG in this population?
. 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?
In a population of flowers growing in a meadow, C1C1 and C2C2 are autosomal codominant alleles that control flower color. The alleles are polymorphic in the population, with ff (C1)(C1) = 0.8 and ff (C2)(C2) = 0.2. Flowers that are C1C1C1C1 are yellow, orange flowers are C1C2C1C2, and C2C2C2C2 flowers are red. A storm blows a new species of hungry insects into the meadow, and they begin to eat yellow and orange flowers but not red flowers. The predation exerts strong natural selection on the flower population, resulting in relative fitness values of C1C1C1C1 = 0.30, C1C2C1C2 = 0.60, and C2C2C2C2 = 1.0. A. Assuming the population begins in H−WH−W equilibrium, what is C1C1 allele frequency after one generation of natural selection? B.Assuming the population begins in H−WH−W equilibrium, what is C2C2 allele frequency after one generation of natural selection? C.
In a container/tub, place 50 pieces of red paper, 50 pieces of pink paper, and 50 pieces of white paper. Let us assume that each color is the phenotypic expression of the genotypes homozygous dominant AA (red), heterozygous Aa (pink), and homozygous recessive aa (white). Without looking, randomly pick 20 pieces of paper from your container/tub and assume that those individuals died upon picking, thus will be removed from your population. a. What will happen to your genotypic and allelic frequencies if 10 white individuals leave your gene pool and 10 red individuals immigrated to your gene pool? b. What will happen to your genotypic and allelic frequencies if by accident, all 33 red (AA) individuals were wiped out by a catastrophe?
In a population at genetic equilibrium, the frequency of the dominant phenotype is 0.96. What are the frequencies of the dominant (A) and recessive (a) alleles, and what are the expected frequencies of the AA, Aa, and aa genotypes?
The ability to taste the compound PTC is controlled by a dominant allele T, while individuals homozygous for the recessive allele (t) cannot taste PTC. In a population consisting of 500 individuals, 347 are tasters and 153 are non-PTC tasters. Calculate the frequency of the T and t alleles in this population, and frequency of the genotypes. (Please train yourself to use the Hardy-Weinberg equation.)
In a population of 200 people, an allele F has a frequency of 84%. What is the frequency of allele f? Using the Hardy-Weinberg equation, estimate the numbers of homozygous dominant, heterozygous, and homozygous recessive genotypes. (Remember that the formula is: p2 + 2pq + q2 = 1, where p represents the dominant allele and q represents the recessive allele.) *Be sure to account for all 200 people in the population.
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 genotype
