Chapter 25, Problem 22PDQ

A farmer plants transgenic Bt corn that is genetically modified to produce its own insecticide. Of the com borer larvae feeding on these Bt crop plants, only 10 percent survive unless they have at least one copy of the dominant resistance allele B that confers resistance to the Bt insecticide. When the farmer first plants Bt com, the frequency of the B resistance allele in the corn borer population is 0.02. What will be the frequency of the resistance allele after one generation of corn borers have fed on Bt corn?

A meadow is home to a population of plants of a particular species. Among these individuals are 125 plants that have red flowers and 375 plants that have white flowers. The allele of the flower color gene that produces red flowers (R) is completely dominant over the white flower color allele (r). Approximately what percent of the plants in the meadow would be expected to have the Rr genotype? a- 23%   b- 33% c- 2% d- 76%
A mountain region has a population of 5,000 mountain goats.  You score these animals for the R locus and find that this locus has two alleles, R (dominant) and r (recessive).  3200 individuals are homozygous dominant, 1,600 are heterozygous, and 200 are homozygous recessive.  A deadly virus infects all of the RR mountain goats in the population (above), killing all individuals of this genotype and leaving the population with only the rr and Rr mountain goats. a) Calculate the new allele frequencies for this population. Show your work.  b) Calculate the new (observed) genotypic frequencies for this population. Show your work.  c) Does this population still appear to be at H-W equilibrium? Why or why not? (You do not need to analyze this statistically).
Imagine that the volcano on Mt. St. Helens erupts again.  All life is removed from the side of the mountain and has to recolonize. Your first task as a geneticist for United States Forest Service is to estimate the frequency of the red allele in the lupine plants that colonize the site. You know that the lupine seeds came from a nearby population where the frequency of the red allele has consistently been approximately 0.2 for many generations. However, in the first year (i.e. first generation, before any local reproduction) on Mt. St. Helens, the red allele of this newly colonized population has a frequency of 0.9. What is the most likely explanation for this difference in allele frequency from the nearby population?
