Give the Hardy–Weinberg expected genotypic frequencies for an autosomal locus with three alleles, where the frequencies of alleles A1, A2, and A3 are defined as p, q, and r, respectively. Set the problem up and show your work. Tay–Sachs disease is an autosomal recessive disorder. Among Ashkenazi Jews, the frequency of Tay–Sachs disease is 1 in 3600. If the Ashkenazi population is mating randomly for the Tay–Sachs gene, what proportion of the population consists of heterozygous carriers of the Tay–Sachs...

3. Consider two loci. One locus has two alleles, A1 and A2 at frequencies p = 0.3 and q = 0.7, respectively, and the other locus has two alleles, B1 and B2 at frequencies r = 0.4 and s = 0.6. (A) What are the possible genotypes of gametes made by organisms in this population? (B) What will be the frequencies of gametes produced by individuals in this population if the two loci are in gametic equilibrium (meaning that they...

A gene has four alleles, A1, A2, A3, and A4. The alleles occur in a population at the following frequencies: A1=0.2, A2=0.1, A3=0.4, A4=0.3. Compute the following: a) Probability that a single allele chosen at random is either A1 or A4 b) Probability than an individual as two A1 alleles c) Probability that an individual has one A1 and one A3 allele d) Probability that an individual is NOT A1A1 e) Probability that if we drew two individuals at random,...

Assume that the allele frequencies of alleles A1 and A2 were 0.2
and 0.8 in one subpopulation and 0.4 and 0.6 in another
subpopulation. Assuming that there are Hardy-Weinberg proportions
within each subpopulation and that the subpopulations are of equal
size, what would be the observed heterozygosity if these
populations were lumped? How does this compare to what would be
expected if there were one random-mating population?? Calculate the
same values for the three heterozygotes when the subpopulations had
frequencies...

In the horse, the A locus governs the distribution of pigment in the coat. The A locus has a series of multiple alleles. These alleles control the following phenotypes: A+ = wild type (bay), A = dark bay (black mane and white tail), a1 = seal brown, a = recessive black. The order of dominance is A+>A>a1>a. If, in a certain population, the allele frequencies are A+ = 0.4, A = 0.2, a1 = 0.1, and a = 0.3, calculate...

Question 2: In an outbreeding diploid population, an autosomal locus has two alleles, A1 and A2. You observe the allele frequencies of A1 and A2 are both equal to 0.5, and the relative fitnesses of the three genotypes (A1A1, A1A2, and A2A2) are equal to 2, 1.5, and 1, respectively. A) Which allele will become fixed in this population? (1 point) **The recessive beneficial allele A2A2 will eventually become fixed in the population (A2A2=1) B) What is the allele frequency...

9. For a fuzzy system with double inputs and single output, x and y are the inputs, z is the output. Assume that the elements of the inputs and output in fuzzy domains are X-fa1,a2,a3), Y={b1,b2,b3}, Z-(c1,c2,c3}, respectively. The relation between inputs and output can be described by the following fuzzy rules: Ifx is A1 and y is B1, then z is C1, where A1 and C1 B2 0.7 0.5 0.2 + a3 0.3 0.4 0.9 0.6 0.8 0.1 b1...

4. Say we have a population, with Ne = 100, containing two alleles, A1 and A2 at frequencies 0.6 and 0.4, respectively. We leave this population alone for 10000 generations (keeping its size constant), then come back to find that the allele frequencies are still 0.6 and 0.4. a) Explain why this would be evidence that selection is acting in this population. b) Which genotype would you expect to have the highest fitness in this case? Explain.

At a bi-allelic locus, alleles A1 and A2 have frequencies p = 1/4 and and q = 3/4. Relative to the current generation, F is 1/2. What is the frequency of genotype A1A1?
3. Consider two loci. One locus has two alleles, A1 and A2 at frequencies p = 0.3 and q = 0.7, respectively, and the other locus has two alleles, B1 and B2 at frequencies r = 0.4 and s = 0.6.
