The hue of lizard scales is controlled by complete dominance, with green scales being dominant over blue scales. Out of a population of 900 lizards, 600 have the GG genotype, 200 have the Gg genotype, and 100 have the gg genotype. Calculate the frequencies of the dominant and recessive alleles, as well as the frequencies of individuals with dominant, heterozygous, and recessive genotypes. Is this population Hardy-Weinberg equilibrium? Justify your answer by performing a chi-square goodness of fit test. For the following problem please refer to the following significance table: Degrees of freedom (n) 1 2 3 4 5% Probability Value (P) 3.84 5.99 7.81 9.49

in sheep, black wool is determined by a Dominant Allele (B) and white wool by a Recessive Allele (b). In a population of 200 sheep, 128 of them exhibit the dominant trait of having black wool and the rest have the recessive trait of white wool. Calculate the frequencies of both the (B) and (b) alleles. Calculate the frequencies of homozygous dominant vs.heterozygous sheep, as well as the homozygous recessives individuals.
In garden pea plants, the yellow seed colour (Y) is dominant over the green seed colour (y). In a population of 24 pea plants, 15 pea plants are homozygous dominant, 6 are heterozygous dominant, and 3 are recessive. Find the frequency of the following YY, Yy, yy. Show all work and record your response using three significant digits.
In a population of 500 individuals in Near East, the frequencies of the dominant and recessive alleles for autosomal recessive genetic disease PKU are 0,89 and 0,11 respectively. A is used to indicate the dominant allele, a is used to indicate the recessive allele. Assuming random mating, what are the expected genotype frequencies?

Calculate the frequencies of the AA, Aa and aa genotypes after one generation if the initialpopulation consists of 0.2 AA, 0.6 Aa and 0.2 aa genotypes and meets the requirements ofthe Hardy-Weinberg relationship. What genotype frequencies will occur after a secondgeneration?
A 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.

In a population of mice, there are two alleles of the Alocus (A1 and A2). Tests showed that, in this population,there are 384 mice of genotype A1/A1, 210 of A1/A2 , and260 of A2/A2. What are the frequencies of the two allelesin the population?
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.
Using the HardyWeinberg Law in Human Genetics In a given population, the frequencies of the four phenotypic classes of the ABO blood groups are found to be A = 0.33, B = 0.33, AB = 0.18, and i = 0.16. What is the frequency of the i allele?
In a population of snails, two alleles, T and t, affect the thickness of the shell, and the degree to which the snails are protected from predation. TT individuals have thick shells, which repel predators, and survive best. Tt individuals have medium shell thickness and survive 88% as well as do TT individuals. tt individuals have thin shells and are easy for predators to eat; they survive only 14% as well as do TT individuals. In a population of gametes at the start of a generation, the frequency of the t allele is 0.23. What is the frequency of the t allele in the gametes that will produce the next generation? 91% 77% 23% 18% cannot calculate with the information given 34%
Under the above conditions of reproductive discrimination against those with attached earlobes, if the population in this next generation is still 500,000 people, then the new genotypic frequencies will be: Homozygous dominants, unattached ear lobes: 0.34 Heterozygotes, unattached ear lobes: 0.48 Homozygous recessives, attached ear lobes: 0.18 What will be the allele frequencies for L and l in this generation? Did the frequency of the recessive allele (l), as compared to its frequency calculated in Part B, increase or decrease because of its deleterious effects on fitness? Does the possession of the recessive allele kill those who possess it? If those with attached ear lobes continue to be only half as successful in securing mates in each successive generation, what will happen to the frequency of the recessive allele in this population?
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.
