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.

How Can We Measure Allele Frequencies in Populations? The MN blood group is a single-gene, two-allele system in which each allele is codominant. Why are such codominant alleles ideal for studies of allele frequencies in a population?
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.

. In pea plants, height is controlled by a Dominant Allele (T) for Tall Height and by a Recessive Allele (t) for Short Height. If 96% of a population of pea plants have the tall phenotype, calculate the frequencies of dominant allele (T) & recessive (t) alleles. Out of the 96%, what is the estimation of how many are homozygous dominant vs. heterozygous? What is the frequency of the recessive phenotype?
Given a population of 100 individuals where 15 are AA, 25 are Aa, and 60 are aa, what is the frequency of allele "A"and the frequency of allele "a"
A very large population of randomly-mating laboratory mice contains 35% white mice. White coloring is caused by the recessive genotype, "aa". Calculate allelic and genotypic frequencies for this population. recessive allele or q equals? dominant allele or p equals? homozygous dominant or p squared? heterozygous dominant or 2pq? recessive or q squared?
In a lab population of mice, a locus affecting fur color has 2 alleles. The B allele produces brown fur, while the b allele produces white fur. Heterozygote individuals (Bb) have beige fur. In a sample of 150 mice, 48 mice have white fur, and 13 have beige fur. What is the frequency of the B allele? Answer with two decimals precision (0.00).
The Allen's and Bergmann's rule can help to explain variation between regional populations for which of the following phenotypes? Group of answer choices Nose form Stature (height) Milk sugar digestion Skin, hair and eye color Intelligence
A hypothethical population of 10,000 humans has 6,840 individuals with the blood type AA, 2,860 individuals with blood type AB and 300 individuals with the blood type BB. What is the frequency of each genotype in this population? AA = AB = BB = What is the frequency of the A allele? What is the frequency of the B allele?
A population of mice in Northern Iowa has two alleles for coat color, B and b. The population has 980 BB, 840 Bb, and 180 bb individuals. What are the genotype frequencies in this population?
In corn, yellow kernel color is governed by a dominant allele for white color, W, and by its recessive allele, w, . A random sample of 100 kernels from a population that is in equilibrium reveals that 9 are yellow and 91 are white. What are the frequencies of the yellow and white alleles in this population? What is the percentage of the heterozygotes?
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.
