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 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. (Please train yourself to use the Hardy-Weinberg equation.) To present your answers, follow the format in the picture below.
The type of plumage found in mallard ducks is determined by three alleles at a single locus: MR, which encodes restricted plumage; M, which encodes mallard plumage; and md which encodes dusky plumage. The restricted phenotype is dominant over mallard and dusky; mallard is dominant over dusky (MR>M>md). If a duck with the restricted phenotype mates with a mallard type and their offspring ratios are 2 restricted, 4 mallard and 4 dusky, then what is genotype of the parents?

Assume Hardy-Weinberg conditions. In the American Caucasian population approximately 70% of people can taste the chemical phenylthiocarbamide (PTC) (the dominant phenotype), while 30% are non-tasters (the recessive phenotype).

A new kind of tulip is produced that develops only purple or pink flowers. Assume that flower color is controlled by a single-gene locus and that the purple allele (C) is dominant to the pink allele (c). A random sample of 1000 tulips from a large cultivated field yields 847 purple flowers (out of which 476 are heterozygous) and 153 pink flowers. If p = frequency of C allele and q = frequency of the c allele. Calculate p and q. A. p = 0.4 q = 0.6 B. p = 0.61 q = 0.39 C. p = 0.847 q = 0.153 D. p = 0.82 q = 0.18

Suppose a geneticist is using a three-point test cross to map three linked rabbit morphology and behavioral mutations called si, It, and Le. The gene si is associated with the silky fur phenotype, and It is associated with the long-tailed phenotype. Both si and It are recessive mutations with respect to wild type. Le is a dominant mutation that confers the lethargic phenotype. The geneticist first crosses true-breeding lethargic rabbits to true-breeding silky fur, long-tailed rabbits. Next, the geneticist backcrosses the Fj progeny to the silky fur, long-tailed parents, and obtains the results reported in the table. Phenotype Number lethargic 815 silky fur, long-tailed 807 long-tailed 177 silky fur, lethargic 179 silky fur 7 long-tailed, lethargic 5 silky fur, long-tailed, lethargic 29 wild type 29 Place the genes in the correct order in the chromosome.

Suppose that in unicorns, two autosomal loci interact to determine the type of tail. One locus controls whether a tail is present at all. The allele for a tail, T, is dominant over the allele for no tail, t. If a unicorn has a tail, then alleles with an unknown dominance relationship at a second locus determine whether the tail is curly or straight. Define the alleles for tail texture as U for a straight tail and U for a curly tail. S Farmer Baldridge has two unicorns with curly tails. When he crosses them, one-half of the progeny have curly tails, one-quarter have straight tails, and one-quarter do not have a tail. What are the genotypes of the parents at the tail-presence gene?

A total of 1000 members of a Central American population are typed for the ABO blood group. In the sample, 421 have blood type A, 168 have blood type B, 336 have blood type O, and 75 have blood type AB. Part A Use this information to determine the frequency of ABO blood group alleles in the sample. Recall that when considering genes with three alleles whose frequencies are represented by the variables p, q, and r, the sum of genotype frequencies resulting from trinomial expansion is: (p+q+r)² =p² + 2pq+q2+2pr+r²+2gr = 1
Suppose a geneticist is using a three-point test cross to map three linked rabbit morphology and behavioral mutations called si, sf, and H. The gene si is associated with the silky fur phenotype, and sf is associated with the short-footed phenotype. Both si and sf are recessive mutations with respect to wild type. H is a dominant mutation that confers the hyper phenotype. The geneticist first crosses true-breeding hyper rabbits to true-breeding silky fur, short-footed rabbits. Next, the geneticist backcrosses the F₁ progeny to the silky fur, short-footed parents, and obtains the results reported in the table.
