A population that we know to be in HWE has the following allele frequencies:
Allele Frequency
A1 0.1
A2 0.3
A3 0.6
1. If you sample one individual at random from this population, what is the probability that it will be a heterozygote? (Show your work;
Homework Answers
As given in the question,
Frequency of the A1 allele = 0.1
Frequency of A2 allele = 0.3
Frequency of A3 allele = 0.6
According to Hardy Weinberg equilibrium for three alleles,
the frequency of heterozygotes in the population can be depicted by = 2A1A2 + 2 A2A3 + 2A3A1
Therefore, 2 * (0.1*0.3) + 2(0.3*0.6) + 2(0.6*0.1)
= 0.06 + 0.36 + 0.12
= 0.54
So from this we conclude that in every 100 individuals 54 will be heterozygotes, hence at random, if an individual is picked, then the probability of that individual to be heterozygote is 0.54 (Answer ).

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...

2. Which of the following correctly describes how inbreeding will affect genotype and allele frequencies in Hardy-Weinberg populations? Genotype and allele frequencies will be unaffected. The frequency of heterozygotes will decrease, but allele frequencies will be unaffected. The frequency of homozygotes will increase, and deleterious alleles will decrease. Beneficial alleles will increase in frequency, as well as the genotypes containing those alleles. Genotype frequencies will return to H-W expectations after 1 generation of random mating. 3. Consider a population with...

In a population, the melanic, black-colored seagull, is due to a dominant allele. Mm and MM individuals are black, and mm individuals are white. In each population, 81 individuals are white-colored, with 19 black- colored individuals. Assuming HWE, what is the approximate frequency of the melanic (M) allele in the population? In class, we took the square root of .81 to get the frequency of the recessive allele, but I don't know how that could be the frequency of the...

You are studying a population of milkweeds and you find the following allele frequencies: f(A1A1) = 0.36 f(A1A2) = 0.48 f(A2A2) = 0.16 If the fitness of the heterozygote (w12) is 0.9 and the average fitness of the population is 0.916, what do we expect the new frequency of the heterozygote genotype to be in the next generation?

In a large random-mating population of lab mice, the A1 allele is dominate and individuals that express this phenotype have a higher fitness than the A2A2 wild-type mice. The fitnesses are 1 and .75 respectively. Initially the allele frequencies are A1=0.4 and A2=0.6 Assume each generation has 100 zygotes form In the first generation, how many individuals will fail to reproduce? What will the new frequencies of the A1 allele be?

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...

A mainland population of 1000 blue iguanas have the neutral alleles A1 and A2 with frequencies of A1 = 0.50 and A2 = 0.50. A new population of blue iguanas is founded on Lizard Island with a population size of 10 males and 15 females. The neutral alleles A1 and A2 are present in the population with frequencies of A1 = 0.30 and A2 = 0.70. Migrants begin moving from the mainland to Lizard Island at a rate of 1...
