Humans carry the dominant allele T can taste the bitter substance PTC, while tt homozygotes cannot. In a population where the frequency of the T allele is 0.4, what is the probability that a particular taster is a heterozygote?
Please explain the answer.
Homework Answers
Given that,
Frequency of Taster allele, T = Fr(T) = p = 0.4
q = 1 - p = 1 - 0.4 = 0.6
Thus the frequency of the non-taster allele, t, in the population = q = 0.6
Therefore, frequency of Heterozygotes = 2pq = 2 * p * q = 2 * 0.4 * 0.6 = 0.48
Since both, Homozygous Dominant individuals and Heterozygous individuals can taste PTC:
Frequency of Tasters = p2 + 2pq = 0.4 * 0.4 + 0.48 = 0.16 + 0.48 = 0.64
Probability that a taster is a heterozygote = Frequency of Heterozygotes / Frequency of Tasters
= 0.48/0.64
= 0.75
The probability that a taster is Hetrozygous is 0.75 or 75%

The compound phenylthiocarbamide (PTC) tastes very bitter to most people. The inability to taste PTC is controlled by a single autosomal recessive allele. In the American white population, about 70% can taste PTC while 30% cannot (are non-tasters). Estimate the frequencies of the Taster (T) and non-taster (t) alleles in this population. How common are carriers (those carrying the allele, but not displaying the phenotype) of the non-taster allele? What assumption did you make to carry out your calculations how...

6. About 70% of Americans get a bitter taste from the substance called phenylthiocarbamide (PTC). It is tasteless to the rest. The "taster" allele is dominant to non-taster. Also, normal skin pigmentation is dominant to albino. A normally pigmented woman who is taste-blind for PTC has an albino-taster father. She marries an albino man who is a taster, though the man's mother is a non-taster. 1 pt A. What are the genotypes of the woman and man? B. What phenotypes...

Phenylthiocarbamide (PTC) is an organosulfur thiourea that has an excessively bitter taste to some individuals and is virtually tasteless to others. This taste response is due to a single gene, where the tasting allele (T) is dominant to the non-tasting allele (t). a. If two tasters that are both heterozygous at the tasting locus have 6 children, what is the probability that they are: non-taster, non-taster, taster, taster, taster and taster in that exact order? b. What is the probability...

The ability to taste the chemical phenylthiocarbamide (PTC) results from a dominant allele (T) and not being able to taste PTC is the result of having two recessive alleles (t). The ability to roll one's tongue is the result of a dominant allele on a second gene (R). Consider that two parents who are both taster, rollers have a child that is a non-taster, non-roller. What is the probability that their next child will have the same phenotype as the...

The ability to taste the bitter compound phenylthiocarbamide (PTC) is an autosomal dominant trait. The inability to taste PTC is a recessive condition. In a sample of 500 people, 391 have the ability to taste PTC and 109 do not. Calculate the frequency of: A. the recessive allele. Express your answer using two decimal places. B.the dominant allele. Express your answer using two decimal places. C.the homozygous dominant genotype. Express your answer using two decimal places. D.the homozygous recessive genotype....

(3) Some people can taste the bitter compound phenylthiocarbamide while others cannot. This trait is governed by a single autosomal gene; the allele for tasting is completely dominant with respect to the allele for nontasting. Among 1707 Hawaiians tested for the ability to taste, 1326 tasters were found. Assuming that the population is at Hardy-Weinberg equilibrium for this gene and that mating is purely random: a. What are the allele frequencies for the tasting allele T and for the nontasting...

2. Ability to taste phenylthiocarbamide (PTC) is mostly determined by the gene PTC. The letters T and t are used here to simplify analysis. TT individuals taste a strong bitter taste; Tt people experience a slightly bitter taste: tt individuals taste nothing. A fifth-grade class of 20 students tastes PTC that has been applied to small pieces of paper, rating the experience as “very yucky” (TT), “I can taste it” (Tt), and “I can’t taste it” (tt).
