A population has the following genotypic distribution: 10AA 15Aa 25aa. Based on your calculated allele frequencies, how many individuals would you expect to be homozygous dominant (=AA) if the population is in H-W equilibrium? Based on your calculated allele frequencies, how many individuals would you expect to be heterozygous (=Aa) if the population is in H-W equilibrium? Based on your calculated allele frequencies, how many individuals would you expect to be homozygous recessive (=aa) if the population is in H-W equilibrium?Is this population in H-W equilibrium? Is it evolving?

A small portion of a population migrates to an isolated island. Its genotypic frequencies are 0.8 AA, 0.1 Aa and 0.1 aa. These individuals start a new population on this island. What phenomenon is being described here? Calculate the allele frequencies for this new island population. Assume that this population is not undergoing evolution and undergoes random mating. What genotypic frequencies will you see in this population after one generation of random mating? What will the allele and genotype frequencies...

Question 6: Calculate the genotypic frequencies that you would expect if the population is in Hardy-Weinberg equilibrium. (Remember, that we are preparing to use the Chi-square goodness-of-fit test to determine if this population is in fact in Hardy-Weinberg equilibrium). Round your answer to three decimal places and submit your answer in the correct format (e.g. 0.062). (a) The frequency of the SS genotype is: (b) The frequency of the Ss genotype is: (c) The frequency of the ss genotype is:...

Allele frequencies at a wing length locus are measured for a natural population of a migratory cricket species as P(A1) = 0.4 and Q (A2) = 0.6. Observed genotype frequencies in the field population are shown below. Compute the expected frequency of the three genotypes if the population is in Hardy-Weinberg Equilibrium for this locus? Observed frequency Expected frequency Show your work A1A1 = 0.28 A1A2 = 0.22 A2A2 = 0.50 The...

Suppose you used allozymes to estimate allele and genotype frequencies in a natural population as we discussed in class. Now suppose there were a number of silent mutations occurring. Can these be detected using allozymes? What influence would the presence of silent mutations have on your estimates of allele and genotype frequencies from allozyme data?

a) How is the Hardy–Weinberg Model used to describe allele and genotype frequencies in a Population Gene Pool? b) Explain how Natural Selection drives Allele Frequency Change in populations c) Name and explain the three different impacts of selection on a population.

Describe how allele frequencies change due to random genetic drift in a small population versus a large population, showing an example of calculating the probability of drift leading to loss of an allele in a small diploid population of size 10, versus a population of size 100.

A population of humans contains the following frequencies for the A, B and O alleles at the I blood type locus: A = 0.6, B = 0.2 and O = 0.2. A female of blood type A marries a type B male. What is the probability that they produce an offspring of blood-type AB?
