Use the Hardy–Weinberg principle to solve problems involving populations.

A population of squid has 50 AA individuals, 20 Aa individuals, and 30 aa individuals.  (a) Calculate the observed f(A) and f(a) for this population. Show your work and clearly indicate your final answers.     (b) Calculate the observed f(AA), f(Aa), and f(aa) for this population. Show your work and clearly indicate your final answers.     (c) Calculate the expected genotype frequencies if the population is in Hardy-Weinberg equilibrium. Show your work and clearly indicate your final answers.     (d) Does this population appear to be in Hardy-Weinberg equilibrium? Why or why not? Be specific in your explanation.

What drives the most the Shannon-Wiener index? The Evenness or the number of species?

Suppose that a certain population of salamanders shows (by electrophoretic analysis) genetic variation for a certain enzyme, and that the enzyme appears to be coded by a single gene with two alleles (Ef, Es). Also suppose that the frequency of the two alleles in the population are estimated as p = frequency of Ef = 0.60, q = frequency of Es = 0. 40. Assuming that the population is in Hardy-Weinberg Equilibrium (i.e., all the assumptions of the Hardy-Weinberg model are met), estimate the expected frequency of all possible genotypes in the population.

Consider the B locus which has two alleles in a population: B and b. Researchers examined the genotypes several individuals for this locus and obtained the following numbers  B/B: 302individuals B/b: 56individuals b/b: 17individuals If the B locus is at Hardy-Weinberg equilibrium, what would the expected number of individuals with the Bb genotype? Round your answer to the closest full number.

I am testing the prediction that spiders with colors that match a flower (cryptic coloration) will have greater success hunting bees visiting that flower. I set up two treatments for spiders: those matching their flower and those not matching their flower. I measure how long it takes each of them to catch a bee. What kind of statistical test would be best for testing my prediction? Chi-square ●ANOVA Regression

What are the conditions for an ideal population as required in the Hardy Weinberg equilibrium?

Give typed full explanation  When a continuous distribution (normal or bell shaped) of a trait is observed in a population, that trait is likely to be …

The next several questions refer to the data given in this problem. You sample a population of leafhoppers and genotype 250 individuals at a polymorphic locus with two alleles. You obtain the following numbers: AA = 68 individuals Aa = 54 individuals aa = 128 individuals What is the expected frequency of the AA genotype if the population is in Hardy-Weinberg equilibrium( you may round your answer to 3 decimal places) What is the expected frequency of the aa genotype of the population is in Hardy-Weinberg equilibrium? ( You may round your answer to 3 decimal places)

The number of homozygous hitchhiker thumb individuals (a dominant trait) in a population of 100 is 9 while heterozygote's number 48. Calculate the frequency of both alleles and identify if this population is in Hardy-Weinberg equilibrium (show your work).
