- How 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?How 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.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?

What is the observed frequency of the homozygous dominant individuals? [ Select] What is the observed frequency of the "r" allele? [ Select ] What is the expected frequency of the heterozygous genotype? [ Select ] If the Chi-squared value for this system is 2.40, is the population in Hardy-Weinberg equilibrium? Why? (note: the critical values for this test is 3.84), [Select ]The frequency of the dominant allele “A” in an imaginary population is 0.20 (p) and the frequency of the recessive allele “a” in the population is 0.80 (q).

- The color distribution for a specific population of snakes is 160 blue, 50 turquoise, and 40 green. The allele for the color blue is represented by B", whereas the allele for the color green is represented by BC. Both alleles demonstrate incomplete dominance. What are the genotype frequencies in the population? Calculate to at least two decimal places. BBBB : BBBG : BGBG. What is the allele frequency of B5 in this population? Calculate to at least two decimal places. allele frequency of BB:Under the above conditions of reproductive discrimination against those with attached earlobes, if the population in this next generation is still 500,000 people, then the new genotypic frequencies will be: Homozygous dominants, unattached ear lobes: 0.34 Heterozygotes, unattached ear lobes: 0.48 Homozygous recessives, attached ear lobes: 0.18 What will be the allele frequencies for L and l in this generation? Did the frequency of the recessive allele (l), as compared to its frequency calculated in Part B, increase or decrease because of its deleterious effects on fitness? Does the possession of the recessive allele kill those who possess it? If those with attached ear lobes continue to be only half as successful in securing mates in each successive generation, what will happen to the frequency of the recessive allele in this population?A population is made up of individuals where 77 have the A1A1 genotype, 65 have the A1A2 genotype, and 123 have the A2A2 genotype.

- The ability to breathe fire in dragons is controlled by a single gene with two alleles. The fire-breathing allele (F) is dominant to the non-fire breathing allele (f) In a population of 600 dragons, 150 dragons are non-fire breathing (ff) and the rest can breathe fire (either FF or Ff). The population is in Hardy-Weinberg equilibrium. The frequency of the dominant allele (F) is represented by "p" and the frequency of the recessive allele (f) is represented by "q". Recall the allele frequency is p+q = 1 and the Hardy-Weinburg equation is p2 + 2pq + q2 = 1. 5. +. A. What is the frequency of the recessive allele (f)? Hint: you can figure out the frequency of ff, which is equal to q2, but then you need to solve for q B. What is the frequency of heterozygous indrviduals (Ff) in the bopulation? Hint: this would be equal to 2pq. You already solved for q, so you need to determine p before you can solve for 2pq.A particular recessive genotype shows a frequency of 16 % in a given population .
