Imagine that you compared the observed genotype frequencies in a population to the expected genotype frequencies under Hardy-Weinberg equilibrium using a Chi- squared test and obtained a Chi-squared value of 3.85. If the critical value of the Chi- squared test statistic is 3.81 (at alpha = 0.05), what can you safely conclude about this population: It is evolving It is at Hardy-Weinberg equilibrium It is undergoing genetic drift It is not at Hardy-Weinberg equilibrium there is not enough information to know anything

In a species of lily, the color of the flower's petals is determined by a dominant purple allele (F) or recessive white allele (f). One hundred flowers in Hardy-Weinberg equilibrium were sampled, and only 15% of the population showed the phenotype of white. Which of the following numbers represents the calculated value of the recessive white allele frequency? 0.92 0.39 0.15 0.85

Below is a plot of genotype frequencies in a population. Assuming the population is in Hardy-Weinberg equilibrium, what is the probability that any given individual will have the m allele? 0.8 0.6 0.4 0.2 0.0 BB Bb bb

The Hardy-Weinberg principle states that allele and genotype frequencies remain constant from one generation to the next, as long as specific conditions are met. Choose Yes or No for the conditions that must be met from the providied statement below. 1. Mutations are exponentially occuring   2. All member of the population breed   3. Everyone produces the same number of offspring   4. The population is infinitely large   5. There is no migration in or out of the population   6. No net mutations are occuring   7. Natural selection of beneficial traits is occuring   8. Natural selection is not occuring   9. All mating is completely random   10. Offspring are able to migrate out of the population

In a population that meets Hardy-Weinberg equilibrium, the dominant allele frequency (A) is 0.7. What is the frequency of homozygous recessive individuals?

Consider a population that is in Hardy-Weinberg equilibrium at a locus with two alleles, A and a, at frequencies of p and q, respectively. Assuming the population remains in Hardy-Weinberg equilibrium, what is the expected frequency of Aa heterozygotes after 100 generations? 0.5 p2 2pq O1

Pretend 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…

1)  In smurfs, blue tails are dominant to red tails.  You observe the following distribution in a smurf population: 214 blue tailed individuals genotype BB 37 blue tailed individuals genotype Bb 19 red tailed individuals genotype bb Is this population in HW equilibrium for the blue tail gene?  Show your work.  If the population is not in HW equilibrium, what might me causing the disequilibrium?

Consider 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 0.33

The UNF penguin lab decided to study the elusive polka dot penguin of Patagonia. They trapped a majority of the population using gummy worms as bait and collected the following information. Observed Genotype Frequencies (not in HWE) AA: 0.464 Aa: 0.427 aa: 0.109 If this population was in Hardy-Weinberg Equilibrium, what would be the expected genotype frequency for the heterozygotes? Retain 3 decimal places.
