In a Continent Island model with two populations (one on the continent and one on the island), the island population has a gene frequency of pi = 0.4 for a particular allele, and the continent population has a gene frequency of pc = 0.6 for the same allele. If the migration rate from the continent to the island is m = 0.1, what will be the gene frequency of the allele in the island population after migration has occurred

In southwest Arizona there is a large, isolated population of kangaroo rats with over 1000 individuals and a 50:50 sex ratio. You genotype these kangaroo rats at 10 SNPs. You start this genotyping project in the year 2020. In year 2050, the population undergoes a large population decline to 10 individuals and stays around 10 individuals until the year 2100, at which point you retire (at a very old age). Draw a plot illustrating the allele frequencies of all 10 loci from year 2020 to year 2100. Label all axes clearly! Now draw a second plot similar to that in the question above, except that in the year 2050 the population does not decline, but instead responds to a new selective pressure in the form of a novel disease spreading into the population. The disease is a strong agent of selection and results in considerable mortality. Importantly, 5 of the loci are neutral and the other 5 are linked to genes that play a role in disease resistance. Explain your plots. I need an appropriate…

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

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

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?

In mice, the waltzing allele (w) that causes the mouse to run in circles due to an inner ear defect is recessive to the non-waltzing allele (W).In an ideal mouse population exhibiting Hardy–Weinberg equilibrium of 150 mice, 50% of the alleles are non-waltzing. What is the frequency of the recessive allele?Record your answer as a whole number percentage.

Two populations of snails live on opposite sides of a city.  The frequency of the recessive allele (q) of a trait is 0.1 in the population on the south side of the city and 0.6 in the population on the north side. Some individuals from the north side are moved to the south side.  After migration, 35% of the individuals on the south side are migrants (originally from the north side).  Determine how this migration event affected q in the south side population.  Round to the nearest thousandth.  Express all values as a frequency in the format “0.###” What is the value of m?  What is q in the south side population after migration (aka, q’)?

Calculate selection for the following scenario. In a population of prairie dogs living on a prairie, prairie dogs with genotype AA have 9 offspring per year on average, those with genotype Aa have 5 offspring per year on average, and those with genotype aa have 8 offspring on average. Round selection to the nearest hundredth, report selection as a value ranging from "0.00" to "1.00" • Selection on genotype Aa: • Selection on genotype AA: • Selection on genotype aa: Which genotype has the highest fitness? Fill in the blank with homozygous dominant, heterozygous, or homozygous recessive

An island population of frogs carries a rare allele at a frequency of 0.1. This same allele is present on the mainland at a frequency of 0.4. If the migration rate from the mainland to the island occurs at a rate of m = 0.2, what is the expected frequency of this rare allele on the island after the influx of immigrants?A) 0.0 < q < 0.2B) 0.2 < q < 0.4C) 0.4 < q < 0.6D) 0.6 < q < 0.8E) 0.8 < q < 1.0

For Wright- Fisher population with 500 of population size, it was found that frequency of allele b was 0.7 (B=0.3) in current population. Calculate the probability that B alleles will fix in the population? Show all workings
