Solved in 2 steps
- assume that the new allele is not strongly deleterious and that it will ultimately become fixed (replace the original allele) in the population. tell the story of how and why the new variant becomes fixed. , be sure to state its frequency at three or more points in time, measured in generations.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?A population consists of 20% AA, 30% Aa and 50% aa. What is the frequency of the A allele in this population? Give typing answer with explanation and conclusion
- The frequency of the R allele for round seeds in a certain population of 500 peas wasfound to be 0.45. How many of them had the rrgenotype?In a population 49% are homozygous with genotype tt, find out the gene frequency of alleles T and t.The particular combination of alleles present in a given organism is referred to as a: Locus Gene Genotype Trait Phenotype
- Explain why the sickle cell allele remained in populations that lived in very wet regions, despite it causing harm to people who are homozygous for that allele (i.e. explain the heterozygous advantage).In fruit flies, long wings (L) are dominant over short wings (l).In a population of 20 fruit flies, 5 have LL genotypes, 10 have Ll genotypes, and 5 have ll genotypes.Find the frequency ofa. long-winged fruit flies Answerb. short-winged fruit flies AnswerRecord your answer as a value between 0 and 1 rounded to two decimal places.Give typing answer with explanation and conclusion A population of snails has a deleterious mutation (m) with a mutation rate of 0.01. Heterozygotes with this mutation will show the deleterious phenotype and have a selection coefficient of 0.4. If allele frequencies in the population are M = 0.99 and m = 0.01, will the number of mutant alleles in the next generation increase/decrease/remain the same?
- 60 individuals have the genotype AA28 individuals have the genotype Aa12 individuals have the genotype aaWhat is the frequency of the A allele?Think of how many alleles in total?hint: add up the number of A alleles in this population: AA= 60+60 and Aa= 28.Add those together and divide by the total number of alleles.Clean Forest Phenotype Frequency Allele Frequency Genotype FrequencyCalculate the allele frequency in this population (see table).
