In mice, black fur (W) is dominant over white fur (w). In an ideal mouse population exhibiting Hardy–Weinberg equilibrium, 189 mice out of 215 have white fur. Calculate the number of mice that are heterozygous dominant for the fur colour gene in the population. Express your answer rounded to the nearest whole number.

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 smurfs, blue tails and red tails are codominant to white tails (this is similar to blood type in humans). In a population of 200 smurfs, 6 have white tails, 93 have blue tails, 51 have red tails, and 50 have purple tails. Papa smurf has learned that the frequency of the blue tail allele is 0.53. Is this population in Hardy-Weinberg Equilibrium? Be sure to do a Chi-square test and show your work.
If 80% of a population has a heterozy gous phenotype, and 16% of that population shows a recessive phenotype, is that population in Hardy - Weinberg equilibrium? In other words, does the population obey the rules of H - W? Perform a statistical analysis to determine your final answer.
In a population that is in Hardy-Weinberg equilibrium there is a gene that has only two alleles. If the dominant gene accounts for 70% of the gene pool, what percentage of the population is heterozygous for the trait?
Color in a species of minnows is determined by a single locus with two alleles: D and d. DD individuals are dark, Dd are intermediate, and dd are pale. In a population that is in Hardy–Weinberg equilibrium, we count 29 pale minnows out of 93. How many minnows do you expect to be dark? Round your answer to the closest integer value.
In a hypothetical population which is in Hardy Weinberg equilibrium, the frequency for a recessive allele is 20%. What percentage of the population would be expected to show the dominant trait in the next generation?
Imagine that in squirrels, the gene for brown coat is coded by two alleles, D for dark brown and d for light brown. In a population of squirrels in Central Park, you identified 251 DD, 182 Dd , and 117 dd. What is the frequency of the light brown, d allele? Please use and round to four decimal points.
Consider the B locus which has two alleles in a population: B and b. Researchers examined the genotypes several individuals for this locus and obtained the following numbers B/B: 302individuals B/b: 56individuals b/b: 17individuals If the B locus is at Hardy-Weinberg equilibrium, what would the expected number of individuals with the Bb genotype? Round your answer to the closest full number.
In a given population, 1 out of 400 individuals has cancer caused by a recessive allele g. Assuming the population is in Hardy-Weinberg equilibrium, what is the expected proportion of individuals who are carriers?
In mice, black fur (W) is dominant over white fur (w). In an ideal mouse population exhibiting Hardy–Weinberg equilibrium, 177 mice out of 222 have white fur. Calculate the number of mice that are heterozygous dominant for the fur colour gene in the population. Express your answer rounded to the nearest whole number. Answer
Short eyelashes are dominant to extra-long eye lashes. In a large, randomly mating population with no forces acting to change gene frequencies, 1600 people out of 10000 have extra-long eye lashes. a)What is the number of people in the population who are expected to be heterozygous? Show your calculation below. b) Would the frequency of the extra-long lash allele increase, decrease, or remain the same if long-lashed individuals preferentially mated with each other and no one else? Explain.
If the frequency of a dominant allele “B” in a population is 80%, and assuming genetic equilibrium in this population, what percentage of the offspring in the next generation could be expected to have the heterozygous genotype?
