Summary Introduction
To determine: The frequency of heterozygote, homozygous dominant and homozygous recessive in a population in Hardy Weinberg equilibrium. Population with two alleles for a particular genetic locus, B and b have an allele frequency of B is 0.7.
Introduction: Population represents the group of individual of same species inhabiting the same area. To study the process of evolution at population level, the gene pool or

If there are two alleles, A and a, in a population and the population is at Hardy–Weinberg equilibrium, what frequency of A would produce the greatest frequency of heterozygotes?
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?
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

- 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.arrow_forwardHow 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?arrow_forwardHow Can We Measure Allele Frequencies in Populations?

- 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?arrow_forwardThere 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?arrow_forwardIn a population that is in Hardy-Weinberg equilibrium, 30 % of the individuals are recessive homozygotes for a certain trait. In a population of 25,000, calculate the percentage of homozygous dominant individuals and heterozygous individuals. (Show the solution)arrow_forward
- The spring beauty flower is found in two colors, pink and white. These colors are determined by two alleles at a single locus, where white is dominant over pink. Consider a population in which 34 % of individuals are pink. If the color locus is in Hardy–Weinberg equilibrium, what percentage of individuals are expected to be heterozygotes? Round to the closest full number.arrow_forwardAbout 70 percent of all Caucasians can taste the chemical phenylthiocarbamide, and the remainder cannot. The ability to taste this chemical is determined by the dominant allele T, and the inability to taste is determined by the recessive allele t. If the population is assumed to be in Hardy-Weinberg equilibrium, what is the heterozygotes frequency in this population? a. 0.7 b. 0.4 c. 0.2 d. 0.5arrow_forwardGiven a population with a p of 0.30, what would you predict that the frequency of heterozygotes would be if the population was in Hardy-Weinburg equilibrium?arrow_forward
- 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?arrow_forwardIf the frequency of PKU, an autosomal recessive disease, is 2.7% in males what is the frequency of females with PKU?

You sample 1000 people for this allele and find 772 homozygous normal individuals, 221 heterozygotes, and 7 people homozygous for cystic fibrosis.
