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 Tand t alleles in this population, and the frequency of the genotypes (TT, Tt, and t).

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 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

What kind of test would best determine whether genotypic frequencies match the Hardy-Weinberg model? Group of answer choices Chi-square with three rows (homozygous dominant, heterozygous, homozygous recessive) Chi-square with two rows (dominant and recessive alleles) T-test between homozygous and heterozygous T-test between dominant and recessive alleles
In a population of 2000 gaboon vipers a genetic difference with respect to venom lethality exists at a single locus. The two alleles (V & v) display incomplete dominance. The population consists of 100 homozygous recessive, non-venomous vipers; 800 heterozygous, mildly-venomous vipers; and 1100 homozygous dominant, deadly-venomous vipers. What is the actual frequency of the recessive allele in the population? /
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.)
Orange coat color in cats is due to an X-linked allele (XO) that iscodominant with the allele for black (X+). When genotypes at the orangelocus were determined for a sample of cats in Minneapolis and St. Paul,Minnesota, the following data were obtained:XOXO females 11XOX+ females 70X+X+ females 94XOY males 36X+Y males 112Calculate the frequencies of the XO and X+ alleles for this population.
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
This lab exercise requires that we count certain Mendelian traits among students present in the lab. Your professor will explain each trait being addressed and will then ask students to identify if they are dominant or recessive for that specific trait. The collected traits will then be plugged into the Hardy-Weinberg Equilibrium formula in order to calculate frequency of Homozygous dominant, Heterozygous and Homozygous recessive individuals in the same. p2 + 2pq + q2 = 100 given data: trait: hair swirl 19 individuals total. 10 had the homozygous dominant hair swirl trait: clockwise the nine other were recessive please do a step by step explanation with the calculation using this data, as I am very unfamiliar with what values mean what and the equation itself thank you!
