The ability to taste the compound phenylthiocarbamide (PTC) is controlled by a dominant allele T. Individuals homozygous for the recessive allele t are unable to taste PTC. In a genetics class of 125 students, 88 can taste PTC and 37 cannot. Calculate the frequency of the T and t alleles in this population and the frequency of the genotypes.

The ability to taste the compound PTC is controlled by a dominant allele T, while individuals homozygous for the recessive allele (t) cannot taste PTC. In a population consisting of 500 individuals, 347 are tasters and 153 are non-PTC tasters. Calculate the frequency of the T and t alleles in this population, and frequency of the genotypes.

The ability to taste the compound PTC is controlled by a dominant allele T, while individuals homozygous for the recessive allele t are unable to taste this compound. In a genetics class of 125 students, 88 were able to taste PTC, 37 could not. Calculate the frequency of the T and t alleles in this population, and the frequency of the genotypes (TT, Tt, and tt). Everyone in the class determined whether or not they could taste PTC. a. Number of tasters % tasters (TT+Tt) b. Number of nontasters % nontasters (tt) c. q2 = genotype tt = d. q = frequency of t allele = e. p= 1-q = frequency of T allele = f. p2 = genotype TT = g. 2pq = genotype Tt = %3D

The compound phenylthiocarbamide (PTC) tastes very bitter to most persons. The inability to taste PTC is controlled by a single recessive gene. In the American white population, about 70% can taste PTC while 30% cannot (are non-tasters). Estimate the frequencies of the Taster (T) and nontaster (t) alleles in this population as well as the frequencies of the genotypes.
Hitchhikers thumb is a recessive trait. We'll use: H=non-hitchhikers thumb allele and h=hitchhikers thumb allele. Suppose we sample our Bi 213 class and find that 72 students have a hitchhiker's thumb, while 128 do not. Assume that the class population is in HW-equilibrium with respect to this locus. How many carriers (individuals who carry one copy of the recessive hitchhiker's thumb allele) are there in our class? (Round off your answer to the nearest 1 individual.)
The ability to taste the chemical compound PTC (phenylthiocarbamide) is coded for by a single gene with two alleles. Let T stand for the allele that codes for tasting and t for the allele that codes for non-tasting. This allele exhibits complete dominance, such that heterozygotes can also taste PTC. Suppose that out of a population of 100 students, 70 are tasters. Estimate the allele frequencies and the frequencies of TT, Tt and tt genotypes in the population. Show all your work, and clearly state your logic and any assumptions you make in estimating the frequencies
The ability to taste PTC (Phenylthiocarbamide) is inherited by a single pair of genes and tasting (T) is dominant to non-tasting (t). Among 798 people tested, 60.4% were tasters. Assuming the population is in Hardy-Weinberg equilibrium, calculate the expected allelic frequencies of T and t. How many people tested are expected to have the genotypes TT, Tt, and t? Allele frequency of T Allele frequency of t # of people with genotype TT # of people with genotype Tt # of people with genotype tt
Snow geese (Chen caerulescens) come in two color types, white “snows” and “blues” with dark bodies. A single gene controls coloration, where the dark (“blue”) allele (D) is dominant. A population of 30,012 geese includes 9236 dark individuals. Genetic testing reveals that 7636 of the 9236 dark individuals are heterozygous (Dd). What is the actual frequency of allele d?

In a population of 200 people, an allele F has a frequency of 84%. What is the frequency of allele f? Using the Hardy-Weinberg equation, estimate the numbers of homozygous dominant, heterozygous, and homozygous recessive genotypes. (Remember that the formula is: p2 + 2pq + q2 = 1, where p represents the dominant allele and q represents the recessive allele.) *Be sure to account for all 200 people in the population.
There are three alleles at a gene determining eye color in a population of wild cats, the B allele (brown eyes) is dominant to both the G allele (green eyes) and the Y allele (yellow eyes). The G allele is dominant to the Y allele. In a population of 1000, there are 100 yellow-eyed cats, 400 green-eyed cats, and 500 brown-eyed cats. What is the expected frequency of the Y allele? 0.10 0.01 0.55 0.32 0.71
Rabbit's ears can be either short or floppy, where short ears are dominant over floppy ears. There are 653 individuals in a population. 104 rabbits have floppy ears and 549 have short ears. Calculate the frequency of the dominant and recessive alleles and the frequency of individuals with dominant, heterozygous, and recessive genotypes.
