: In a study with house mice, 93 house mice (Mus musculus) in a single barn in Wiscons focused on a single locus (the gene for a certain enzyme) with two alleles, A and a. The genotype frequencies found were: AA 0.226 Aa 0.400 aa 0.374 a) Calculate the allele frequencies. b) How does this population differ from the predictions of Hardy-Weinberg equilibrium? Show the calculation

Sample  A has been allowed to breed randomly for many generations. At a particular gene locus, there are two alleles, and one is dominant to the other. After several generations, 64% of the animals have the phenotype associated with the dominant allele. Population A is in Hardy-Weinberg Equilibrium.a)  In Colony A, what is the estimated frequency of the recessive allele and heterozygous genotype? Sample B has been studied for many generations. The slope of the regression line describing the relationship between the number of whiskers in an offspring and the average number of whiskers of both parents is 0.50.b)What is the heritability (h2) of abdominal bristle number in Sample B? c) Suppose that the mean whisker number in Sample B is 26 and suppose that the researcher chooses rats for breeding such that the mean whisker number of breeding individuals is 36. What would you expect the mean number of whiskers in the offspring of these breeding individuals to be? Why? d) Precisely why…

A total of 6500 North American Caucasians were blood typed for the MN locus, which is determined by two codominant alleles LM and LN. The following data were obtained: Blood Type M MN N a. 0.52, b. 0.23 a. 0.52, b. 0.12 0.48, 0.12 Number a. What is the allele frequency of LM in the population (LM=p) b. What is the genotypic frequency of LNLN? a. 0.48, b. 0.23 1800 3200 1500

Considering the Hardy-Weinberg theorem’s assumptions, which of the following statements is NOT correct?  (Recall that there are certain assumptions that must be true in order for the Hardy-Weinberg theorem to accurately predict genotype ratios in the next generation.)a) The population must be very large so there random genetic drift will not occur.b) No natural selection can occur.c) Mating must be random.d) Individuals must migrate into and out of the population so that gene flow will occur.e) Mutations must not occur.

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

How do I find the frequency of alleles in this population? Please explain how to solve this problem.
