Unformatted text preview: In Lab this Week • If PV92 didn’t work, make genomic DNA • Set up Crime lab PCR • Practice loading an acrylamide gel • Dump F1 flies from crosses • PV92 data analysis • Sordaria squashes • Polytenes- Foiled by living organisms again! • Clean up! The Hardy-Weinberg Equations p Frequency of one allele. q Frequency of the other allele. Model Consists of Two Equations: 1. Allele frequency: p + q = 1 2. Genotype frequency: p 2 + 2pq + q 2 = 1 Calculating Observed Genotype Frequencies for a Population Observed genotype frequency = # of individuals with a specific genotype/total individuals Genotypes Total Number +/+ 42 +/- 34-/- 78 No Bands 8 Example: Frequency of +/+ genotype = 42 +/+ students/154 total students = 0.273 Calculating Observed Allelic Frequencies for a Population (p and q) Genotypes Total Number +/+ 42 +/- 34-/- 78 No Bands 8 Observed allele frequency: =Number of a certain allele/total alleles Be careful! The total alleles is 2(#of individuals). Each allele is present in homozygotes and heterozygotes....
