Title: A dominant allele, T, codes for the ability to taste the compound PTC...
Post by: nfolkab on May 7, 2012
A dominant allele, T, codes for the ability to taste the compound pheylthiocarbmide (PTC). People who are homozygous for the recessive allele, t, are unable to taste PTC. In a genetics class of 125 students, 88 students and can taste PTC and 37 cannot.
a) calculate the expected frequencies of the T and t alleles in the student population
b) how many students would you expect to be heterozygous for the tasting gene
c) how many students would you expect to be homozygous for the tasting gene

 I found out how to do a, but I dont know how to change the percentages of students into numbers of students in b and c...

Oh god... I did this experiment. My teacher told us if we could taste it, it would be sweet like vanilla. I could taste it. Never liked him much after it... Probably the worst taste ever.
