- What is the Hardy-Weinberg Principle of Equilibrium? Why is it a useful concept? To what does each component (p, q, p2, 2pq, q2) in the equation refer?arrow_forwardThe basis for rejecting any null hypothesis is arbitrary. The researcher can set more or less stringent standards by deciding to raise or lower the p value used to reject or not reject the hypothesis. In the case of the chi-square analysis of genetic crosses, would the use of a standard of p = 0.10 be more or less stringent about not rejecting the null hypothesis? Explain.arrow_forwardThrough PCR, we have determined the PER3 genotypes for a class of students as follows: H4/H4 = 125 individuals; H4/H5 = 90 individuals and H5/H5=85 individuals. Considering the Hardy Weinberg equilibrium and comparing the observed and the expected number of individuals for the three genotypes, calculate the value of the Chi-square statistic.

- Explain the five conditions that need to be met for a population to be at genetic equilibrium according to Hardy and Weinberg (The Hardy-Weinberg principle). Additionally, explain what conditions would have to have been met if the population evolved. Be detailed in your answer(s).arrow_forwardWhat is the expected genotype frequency of the heterozygous genotype under the Hardy-Weinberg equation P = 0.7?arrow_forwardI believe that the correct answer is: p^2+2pq+q^2=1 I just want to make sure that I am understanding the Hardy-Weinberg Equilibrium correctly.arrow_forward
- in the Hardy-Weinberg equation, what do the terms p2, q2, and 2pq represent, in terms of the genetic structure of a population?arrow_forwardThrough PCR, we have determined the PER3 genotypes for a class of students as follows: H4/H4 = 125 individuals; H4/H5 = 90 individuals and H5/H5=85 individuals. Considering the Hardy Weinberg equilibrium and calculating the Chi-square statistic, do you reject or fail to reject the null-hypothesis? 1. Comparing the value of Chi-square that I calculated with the critical value of Chi-square for the appropriate degrees of freedom I conclude that P<0.05. Hence, I reject the null hypothesis. 2. Comparing the value of Chi-square that I calculated with the critical value of Chi-square for the appropriate degrees of freedom I conclude that P>0.05. Hence, I reject the null hypothesis. 3. Comparing the value of Chi-square that I calculated with the critical value of Chi-square for the appropriate degrees of freedom I conclude that P<0.05. Hence, I fail to reject the null hypothesis. 4. Comparing the value of Chi-square that I calculated with the critical value of Chi-square for the…arrow_forwardThere are two existing hypotheses for an unusually high frequency of a deleterious recessive allele in a certain population other than it is hidden in the heterozygous genotype and not exposed to selection. Explain what these two likely hypotheses are and how you could distinguish between them based on your understanding of the applicable assumptions that are part of the Hardy-Weinberg Equilibrium Modelarrow_forward
- please tell us the expected average time to fixation of an allele at frequency p = 0.5 in a population of 100 individuals, we can safely assume that the allele does become fixed?arrow_forwardIn your own words, explain the following concepts and provide at least one example for each: Continuous Variation (Minimum of 2 complete sentences.)arrow_forwardI believe that the answer is p+q=1 under the Hardy-Weinberg Equilibrium.
