Assignment 5 ANT 160 Name Akan Tamem Hardy Weinberg Equilibrium In this exercise, we are going to examine the frequencies of some of our Mendelian traits and test whether our class evolves by looking into the future and seeing if our allele frequencies fluctuate enough that we would consider the population to have evolved. As discussed in Lecture 8, the allele frequency in a population will always add up to 1, so our equation is: p+q=1 where p is the dominant allele and q is the recessive allele. We also know that there are three variants of a gene in a two allele Mendelian trait: homozygous dominant (p 2 ), heterozygous (pq), and homozygous recessive (q 2 ). The sum of each of these variants within a population will also equal 1, giving us the Hardy Weinberg equation: p 2 +2pq+q 2 =1 Following the example in Lecture 8, you will calculate the allele and genotype frequencies within our class for ear lobe types. First, find the class totals for ear lobe types on the Moodle page and fill the table below. Trait Phenotype # with Phenotype Total # of students Phenotype frequency Earlobes Free hanging (p) -------------------- Attached (q) 45 -------------------- 23 68 0.66 ------------------- 0.34 Using the information provided, calculate the allele and genotype frequencies (round to the nearest hundredth), and enter the information below.
