Instructions: Below are two questions covering basic population genetics and natural selection. Each question has some values (denoted by a boldfaced capital letter) that vary by last name; there is a table at the end of the document with all of the values you are to use for a given last name. You should type all of your answers onto the AnswerSheet at the end of this document, but you should include separate sheets (handwritten or typed) showing your calculations. I suggest carrying out all calculations to 3 or more significant digits during the process of solving the problems. All work must be turned in in hardcopy by the START of class on Tuesday October 23. Total Points Possible = 30
1. (5 points total) An online survey found that of 4500 individuals of European ancestry, Asaid they could smell asparagus in their urine and Bsaid they could not.
a. If the Sallele for odor detection is dominant over the Gallele for lack of odor detection, and Cindividuals are heterozygotes, what are the genotype frequencies for this locus, assuming random mating? (1 point)
b. What are the allele frequencies? (2 points)
c. Is the population in Hardy-Weinberg equilibrium? How do you know? (2 points)

Imagine that You are a Nature Conservancy biologist studying two populations of redwoodsorrel ( Orall's oregonal In the coastal forests near Mendocino , CA. Hedwood sorrel Is an understory herb*adapted for low light and moist Environments . It's leaves are among the favored delicacies of slugs and other*forest herbivores . In the two park's you are monitoring , rangers are conducting controlled burns every 5.Years to Encourage the establishment of coast redwood seedlings . Their relatively cool ground fires kill living*"_ aregeng plants , but not their seeds , which readily germinate on the sall layers Exposed by burning .*HEdwood sorrel populations are polymorphic for leaf pattern : Seedlings and adults display one of two leafmorphis ( see table below; . Previous genetic work has shown that a single gene focus LI with two alleles IL .and La| control the leaf polymorphism ."You began a study of two O. pregang populations [Shady Woods andBLE Timber ! just after burns were conducted In 2012 . You searched Exhaustively through Each burn area InDecember 2012 , and new red wood sorrel seedlings were counted and characterized by their leaf patterns ."You also conducted genetic work to distinguish between LILI plants and the homozygotes .
