Using the PTC paper‚ rip off a piece and press it to the tip of your tongue. PTC tasters will sense a bitter taste. These individuals are considered tasters. 2. A number representing the frequency of tasters (p2+2pq) should be calculated by dividing the number of tasters by the total number of students. A number representing the frequency of nontasters (q2) should be obtained by dividing the number of nontasters by the total

2 Single Gene Inheritance WORKING WITH THE FIGURES (The first 14 questions require inspection of text figures.) 1. In the left-hand part of Figure 2-4‚ the red arrows show selfing as pollination within single flowers of one F1 plant. Would the same F2 results be produced by cross-pollinating two different F1 plants? Answer: No‚ the results would be different. While self pollination produces 3 : 1 ratio of yellow versus gene phenotype‚ cross pollination would result in 1 : 1 ratio‚ in

THE VICTORIA SCHOOL SANTIAGO JACOME LAB REPORT PTC BIOLOGY SL AIM: The aim of this lab is to analyze the genotype differences of classmates that are able to taste PTC‚ Thiourea and Sodium benzoate and determine the phenotypes found. Testing the ability to taste PTC has been a mainstay activity in human genetics for generations of teacher and students. The ability to taste PTC is inherited. Traditionally this is presented as a case of simple Mendelian inheritance involving a dominant allele for tasting

DESCRIPTIVE WORDS FOR WINE Wine tasting‚ as a production control technique‚ depends upon converting into words the impression created by the reaction of the wine on the taster ’s palate. In order that one wine‚ tasted by several individuals‚ be reported in the same way by each‚ it is necessary that all of the tasters use the same words for the separate palate impressions the wine creates. The terms used in sensory examination fall naturally under the four headings of appearance‚ color‚ taste
