Document Summary
Understand hardy-weinberg theory and apply to in-class simulation data. Apply chi square test to population data to determine whether populations are in. Preparation read the review material and introduction in this lab manual. Phenylthiocarbamide, or ptc, is a chemical compound that is notable for its duality in taste; it is either bitter and unpleasant or completely tasteless, depending on one"s genetic makeup. Ptc is a dominant genetic trait, meaning an individual needs to possess only one copy of the taster allele to exhibit the taster phenotype. Recall that the phenotype describes the physiological traits of the organism, while the genotype is the organism"s genetic makeup. Approximately 75% of people can taste ptc, though this ranges by ethnicity, from less than 60% in certain racial groups to nearly 100% in others. A single gene, tas2r38, on chromosome 7 has been implicated in the ability to taste ptc (kim et al 2003).
