Assume two alleles A1 and A2 with known frequencies e.g. p (A1) = 0.7, q (A2)= 0.3
What would be the frequency of the A1A2 ?
Step by step
Solved in 2 steps
- Figure out allelic frequencies directly from the genotypic frequencies AA=0.3 Aa= 0.2 aa=0.5.A= a=What is the expected genotype frequency of the homozygous recessive genotype under the Hardy-Weinberg equation P = 0.7? .49 .84 .42 0.09A. 0.0025 B. 0.01 C. 0.95 D. 0.99 E. None of the above The common morning glory (Ipomoea purpurea) is highly polymorphic for flower color. Part of this phenotypic variation is due to allelic variation at the P locus. This locus determines whether flowers will be in purple or white color. Further genetic studies showed that the purple color is dominant. Based on a survey, you found that out of a total of 1000 individuals in the population, 922 are purple and 78 are white. Assuming that this population is in Hardy-Weinberg equilibrium, what is the allele frequency for the purple allele? A. 0.078 B. 0.279 C. 0.721 D. 0.922 E. 0.960

- About 9 percent of Caucasian males are color-blind andcannot distinguish red-colored from green-coloredobjects.a. Offer one genetic model for color blindness.b. Explain why and how color blindness has reached afrequency of 9 percent in this populationUsing the HardyWeinberg Law in Human Genetics In a given population, the frequencies of the four phenotypic classes of the ABO blood groups are found to be A = 0.33, B = 0.33, AB = 0.18, and i = 0.16. What is the frequency of the i allele?The Valyrian elders are doing projections about the future and want to calculate the frequencies of certain genotypes in the next generation. They are only interested in figuring out what proportion of the next generation will bear the signature Valyrian silver hair phenotype. (Assume the allele frequencies remain unchanged from the first part of this question.) A-What will the frequency of the AA genotype be? b-What will the frequency of the Aa genotype be?
