- The following gel represents a result of the RFLP experiment you designed using the DNA of 9 different individuals (this is your population). The ladder used is a 50bp ladder and is loaded in the first well. 1. What is the percentage of non-tasters in this population? 2. What is the percentage of heterozygous in this population? 3. What is the frequency of nontaster allele in this population? 4. What is the frequency of the taster allele in this population?arrow_forwardMany genetic disorders, such as cystic fibrosis and sickle-cell disease are due to mutations in a recessive allele. You have sampled an isolated population in which you know that the percentage of the homozygous recessive genotype (aa) is 36%. Using that 36%, calculate: 1f. the frequency of the dominant phenotype if "A" is completely dominant over "a” (round to the nearest hundredth)arrow_forwardIn addition to the number of trichomes on the leaf petioles, you could alternately select for a different trait--such as the height of the plant at first flower, or leaf color--and choose the individual plants that are at one extreme for this trait to be the parent plants in your experiment. The following data were obtained in an artificial selection experiment with Wisconsin Fast Plants. What is the mean height of the plants in the parent population, rounded to the nearest tenth (0.1)?arrow_forward
- In a population with two alleles at the R locus (R and r), the frequency of the genotype rr is 0.24. Assuming that the R locus is at Hardy-Weinberg equilibrium in this population, what is the frequency of heterozygotes (Rr)? Round and report your answer to the second decimal place (0.00). Your Answer:arrow_forwardIn a lab population of mice, a locus affecting fur color has 2 alleles. The B allele produces brown fur, while the b allele produces white fur. Heterozygote individuals (Bb) have beige fur. In a sample of 150 mice, 48 mice have white fur, and 13 have beige fur. What is the frequency of the B allele? Answer with two decimals precision (0.00).arrow_forwardA population of dragons or Varanus dragonus has two alleles B and P encoding for phenotypes blue and purple scales, is dominant over B. You have population of 345 individuals. PP = 100, BP; =90 , and BB = 155 . What is the frequency of the P allele? Please use and round to four decimal points.arrow_forward
- please plug in 5 and 6 into the hardy weinberg equilibrium formula p2 + 2pq + q2 = 100 to calculate frequency thank you!arrow_forwardPretend that you are comparing the actual genotype distribution for a population with the distribution of genotypes predicted by the Hardy-Weinberg theorem. So your hypothesis is that the population is in Hardy-Weinberg equilibrium (i.e. that actual population data fit the Hardy-Weinberg expectations). If you carry out a chisquare goodness of fit test and calculate a total chisquare value of 0.03 with 1 degree of freedom (see table), what does this mean? (select all true statements)a) The data do NOT fit the hypothesized distribution.b) The data do fit the hypothesized distribution well enough, so we accept the hypothesis at this time (i.e. we cannot reject the hypothesis). c) The probability that the data came from a population in Hardy-Weinberg equilibrium is too small, so we reject the hypothesis.d) The probability that the data came from a population in Hardy-Weinberg equilibrium is too big, so we reject the hypothesis.e) The data support Hardy-Weinberg expectations – there is no…arrow_forwardConsider an autosomal locus with alleles A and a. If the the allele frequencies are as follows Freq(A) = 0.4, Freq(a) = 0.6. , then what is the predicted frequency of heterozygous Aa individuals, assuming the population is in Hardy-Weinberg equilibrium? Freq(Aa) = ? Enter a number between 0 and 1, inclusive, for example 0.33arrow_forward
