- 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?A hypothetical species of plant has flowers whose color is controlled by a single gene with two alleles, blue (B) and yellow (Y), where blue is dominant and yellow is recessive. A population of 2430 of these plants includes 190 plants with yellow flowers.Assuming that the population is in Hardy-Weinberg equilibrium, what is the frequency of the yellow allele?
- In a population of pea plants, there were 20 pea plants with white flowers (pp), 160 were heterozygous with purple flowers (Pp); and 820 were homozygous with purple flowers (PP). What is the frequency of the p allele in the population?Imagine a population 528 individual plants. In this population, 4 % of the plants produce red flowers, and 9 % produce pink flowers. The remaining plants produce white flowers. Flower colour is attributed to a single locus with two alleles. Red flowers are produced by plants that are homozygote for the R allele. White flowers are produced by plants that are homozygote for the W allele. Heterozygotes (RW) produce pink flowers. What is the expected (under Hardy-Weinberg equilibrium) number plants producing pink flowers in this population? Round your answer to the closest full number.Cystic fibrosis is a genetic disease mostly affecting people of European descent that is caused by a recessive allele. You sample 1000 people for this allele and find 772 homozygous normal individuals, 221 heterozygotes, and 7 people homozygous for cystic fibrosis. Is this population in Hardy-Weinberg equilibrium?
- Imagine the following population with the genotype: AA= 15 Aa= 10 aa= 25 What are the OBSERVED genotypic frequencies? (To do this determine the total number of individuals in the population (50) and make a fraction for each genotype.) AA= Aa= aa=In some populations of grasses, the ability to grow in soil sprayed with a certain herbicide is a dominant trait determined by the allele "R". In a population at genetic equilibrium, 91% of the seeds can germinate in sprayed soil. What are the frequencies of "R" and "r"? What percentage of the plant that germinates in the soil will be heterozygotes?In a particular species of flower, C1 codes for red flowers, C2 codes for white, with the heterozygous individuals being pink. A. In the frequency of pink individuals in the population was .7126, would you be able to estimate the frequencies of the individuals alleles in the population? Why or why not? B. If the frequency of red individuals in the population was .329, what would the estimated frequency of pink and white individuals be in the same population?
- In a population of millipedes, the gene “R” determines their color. The color red is determined by the dominant “R” allele and the color orange is determined by the recessive “r” allele. A population of 100 millipedes consists of the following genotypes: 30 RR 44 Rr 26 rr Answer the following - You can represent the ratio/frequency as a fraction or a %. A. What is the genotypic ratio of this population of millipedes? B. What is the phenotypic ratio of this population of millipedes? C. What are the allele frequencies for “R” and “r” in this population of millipedes?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?A scientist is studying a wild population of Japanese morning glories. It is easy to separate genotypes at a flower color locus by their phenotypes. Red individuals are homozygous for the R allele, yellow individuals are homozygous for the Y allele, and orange individuals are heterozygous. If the number of individuals with the following genotypes are: RR: 831 RY: 33 YY: 442 Is the population in Hardy Weinberg Equilibrium?
