For a gene existing in two alleles, what are the allele frequencies when the heterozygote frequency is at its maximum value, assuming Hardy-Weinberg equilibrium? What if there are three alleles?
If the Hardy-Weinberg equation enables us to use information on genotype and allele frequencies to predict the genotype frequencies of the next generation. In a population of 100,000 people carrying the recessive allele a for albinism, there are: 100 aa albinos and 1800 Aa heterozygous carriers.
What is a frequency of heterozygous carriers in the next generation?
Calculate the frequency for the A allele and a allele.
How this will chance the frequency of alleles in a population for the following generation?
If a trait determined by autosomal recessive allele occurs at a frequency of 0.25 in a population, what are the allelic frequencies? Assume Hardy-Weinberg equilibrium and use A and a to symbolize the dominant and recessive alleles, respectively. Show calculation.

- Using the HardyWeinberg Law in Human Genetics Suppose you are monitoring the allelic and genotypic frequencies of the MN blood group locus (see Question 2 for a description of the MN blood group) in a small human population. You find that for 1-year-old children, the genotypic frequencies are MM = 0.25, MN = 0.5, and NN = 0.25, whereas the genotypic frequencies for adults are MM = 0.3, MN = 0.4, and NN = 0.3. a. Compute the M and N allele frequencies for 1-year-olds and adults. b. Are the allele frequencies in equilibrium in this population? c. Are the genotypic frequencies in equilibrium?arrow_forwardHow 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_forward
- How Can We Measure Allele Frequencies in Populations? What are four assumptions of the HardyWeinberg law?arrow_forwardHow 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.arrow_forward. Full color (D) is dominant over dilute color (d). Of 325 cats observed, 194 have full color and 131 have dilute color. a. If the cats are in Hardy-Weinberg equilibrium, what is the frequency of the dilute allele? b. How many of the 194 cats with full color are likely heterozygous?arrow_forward

At hardy-weinburg equilibrium, what is the frequency of the Aa genotype?arrow_forwardIn 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?arrow_forwardIn 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?arrow_forward
- A population of sea cucumbers from the maldives has the following allele frequencies for the tentacle colour gene; A= 0.7 and a=0.3.

What are the genotypic frequencies expected under Hardy-Weinberg equilibrium?arrow_forwardIn corn, kernel color is governed by a dominant allele for white color (W) and by a recessive allele for yellow (w). A random sample of 152 kernels from a population that is in Hardy- Weinberg equilibrium reveals that 35 kernels are yellow and 117 kernels are white. What is the frequency of individuals with the homozygous dominant genotype?arrow_forward
