Question
The first picture is all of the procedures then please fill out the table correctly.
1. Using the PTC test strips, press it to your tongue tip. PTC tasters will sense a bitter taste. For the purpose of this exercise, these individuals are considered to be tasters. 2. A decimal number representing the frequency of tasters should be calculated by dividing the number of tasters in the test subject group by the total number of test subjects. This will be p2 + 2pq in the H-W equation. 3. A decimal number representing the frequency of non-tasters (q' in the H-W equation) should be calculated by dividing the number of non-tasters by the total number of test subjects. Record these numbers in Table 2.1a below. 4. Use the Hardy-Weinberg equation to determine the frequencies (p and q) of the two alleles. The frequency q can be calculated by taking the square root of q'. Once q has been determined, p can be determined because 1 q = p. Record these values in Table 2.1a for the class. 5. Record the non-taster (q²) values (convert % to decimal) from the "Global Variation in Sensitivity to Bitter Tasting PTC Data Graph" for the average European groups and the average African, Asian, and Native American groups. Then calculate the p and q value for each group and the Taster value (p2 + 2pq).
