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?

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.
In corn, yellow kernel color is governed by a dominant allele for white color, W, and by its recessive allele, w, . A random sample of 100 kernels from a population that is in equilibrium reveals that 9 are yellow and 91 are white. What are the frequencies of the yellow and white alleles in this population? What is the percentage of the heterozygotes?
In 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?
. 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 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?
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 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 a human population at equilibrium, three genotypes are present in the following proportions: A/A = 0.81, A/a = 0.18, a/a = 0.01. Answer the following questions: What are the frequencies of gene A and gene a? What will their frequencies be in the next generation? What proportion of all marriages in this population is between heterozygotic parents?
There are 5 individuals in a population. Blue is dominant to orange and there is 1 homozygous dominant, 1 heterozygote, and 3 homozygous recessive individuals. What is the observed allele frequency of the orange allele?
There are 350 dominant homozygotes, 75 heterozygotes, and 40 recessive homozygotes in a population. How many dominant and how many recessive alleles are in this population? What would be their respective allele frequencies?
In a population of snapdragons, at the locus controlling flower color you find that 0.2 are AA, 0.65 are Aa, and 0.15 are aa. Assuming that any deviations from Hardy-Weinberg are due to the system of mating, calculate the inbreeding coefficient.
In a population of 10,000 individuals, where 3600 are MM, 1600 are Mm, and 4800 are mm, what are the frequencies of the M alleles and the m alleles?
