Two populations of equal size exchange migrants at a rate of 0.21. The allele S is found in a frequency of 0.6 in population 1 and in a frequency of 0.2 in population 2. After one generation, what is the allele frequency of S in population 2?

Migrants are moving from a mainland population to an island at an average rate of 50 individuals per generation. The frequency of A2 is 80% on the mainland while 0% of the 1000 individuals currently on the island carry allele A2. Allele A2 turns out to have a selective advantage, such that homozygous individuals reproduce at four times the rate of the native population What is the frequency q" of A2 individuals on the island after selection, but before migration...

An allele, A1, in a diploid population of size N, starts at an allele frequency of 0.7. What is the expected allele frequency in the next generation? In the 100thgeneration? What is the probability that the allele frequency will increase in the next generation? If you follow 100 populations that start with the same conditions for millions of generations, how many would you expect to be fixed for A1?

Consider two populations, I and II, with initial frequencies of q0=0.8 and q0=0.2, respectively. What are the change in gene frequency after one generation and its ultimate value in population I if migration occurs from population II to I at the rate of 3% every generation? How many generations of continuous migration it will take to halve the gene frequency of population I?

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...

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...

Q3.3. Recall the prediction: Allele frequencies change by genetic drift equally quickly in large populations and in small populations. Is this correct? Why or why not? Yes. Genetic drift is sampling error, and sampling error is unpredictable, no matter the population size. Yes. Small populations experience more sampling error, but large populations have more reproduction overall, leading to similar rates of allele frequency change. O No. In the ferret experiments, allele frequencies changed more quickly in the small populations than...

ABO Blood Type allele frequencies: [I^O] = 0.7 , [I^A] = 0.2 , [I^B] = 0.1 For the Rh factor frequencies: [Rh+] = 0.8 , [Rh-] = 0.2 1. In this population what is the frequency of the type "O", Rh positive individuals? 2. The rarest type of blood is type AB Rh negative. How many of these are expected in 1000 individuals? 3.

For this question, we consider a two-allele, one locus trait. Here, assume the trait that this locus affects is coat thickness. In a juvenile population of bison, they commonly experience a harsh winter. The AA individuals lose about 50% of their number, the Aa individuals lose about 30%, and the aa individuals lose about 90% of their number. Before the winter, there are 1000 AA individual, 300 Aa individuals, and 700 aa individuals (generation 1). a) What are the relative...

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...
