BIO 101 SUMMER 2017 Assignment 2 (10 points) STOW ALL YOUR WORK CLEARLY (YOu CAN USE SCRATCH PAPERS FOR YOUR WORK AND THEN REWRITE IN A NEAT MANNER ON THIS PAPER). IF YOUR WORKIS NOT CLEAK TO ME, YOU MAY NOT EARN ANY POINT. Due on Final Exam Date 1) The compound phenylthiocarbamide (PTC) tastes very bitter to most persons. The inability to taste PIC PTC while controlled by a single recessive gene. In the American white population, about 70% can taste 30% cannot (are non-tasters). Estimate the frequencies of the Taster (T) and non-taster (t) alleles in this population as well as the frequencies of the diploid genotypes. The ability to taste PIC is due biology classes at NoVA, and determined that 150 could detet the biter taste of Prc and 0 culd n Calculate all of the potential frequencies. 2) to a single dominate allele "P. Let us say you sampled 200 individuals in

Explanation / Answer

Non-tasters are controlled by single recessive gene that is "tt".
30% of the population is non taster that means q2=0.3
So q=0.5477(t)
And p=1-0.5477=0.4522(T)
2pq= 0.4953(Tt)
Frequency of tasters =0.4522
Frequency of non taster =0.5477
Frequency of diploid genotype
TT(p2) =0.2044
tt(q2)=0.3
Tt(2pq)=0.4953
