You start work at Bonsanto, a new agricultural biotechnology corporation, and they want you to engineer a
strain of corn that can grow during the winter. Just thinking of all the corn chips that could be produced with a
year-round growing season makes you see dollar signs ($$). The first step is to find a population of corn that is
in genetic equilibrium so that you can more easily select for the ability to grow in cold environments. Looking
through the company’s corn population stocks, you think you find one that will be perfect for your research.
You select six (6) cobs of corn from the population and determine the genotype of each kernel on each cob.
Based on the data below for a trait with a single gene locus and two alleles, will you be able to use this
population for your research (i.e. is this corn population in genetic equilibrium)?
In your answer, determine the observed genotype and allele frequencies, the expected genotype frequencies, and
whether or not the population is in genetic equilibrium, showing all of your steps and calculations. Keep your
answers rounded to four decimal places throughout. Write a brief (2-3 sentence) conclusion about the suitability
of this corn population for use in your intended research.
