The ability to taste PTC paper is controlled by a dominant allele. The ability to taste (T) is dominant over the inablity to taste (t). Normal skin (N) is dominant over albino skin (n).

Can ptc paper placed in your mouth determine if your a taster or "non taster"? assuming your a taster what possible genotypes could produce your phenotype ? if you produced children with a "non taster " what genotypic/phenotypic ratios would be excepted in the offspring ?
The ability to detect the bitter taste of Phenylthiocarbamide (PTC) is inherited. “Tasting” is controlled by a dominant allele, while “non-tasting” is recessive PTC paper placed in your mouth can determine if you are a “taster” or a “non-taster”? Let's assume that you are a "taster". What possible genotypes could produce your phenotype? If you produced children with a "non-taster", what genotypic and phenotypic ratios would be expected in your offspring?
Pea PlantsIn pea plants, a round-seed shape (R) is dominant over a wrinkled-seed shape (r). A round-seeded pea plant was crossed with another round-seeded pea plant. What are the genotype(s) and phenotype(s) ratios of the F1 generation? Show all possibilities using Punnett squares. State the F1 generation genotypes and phenotypes.
In humans, hair color and structure are determined by two independent pairs of genes. The dominant gene T determines dark hair color, and the recessive allele t - light hair; The dominant gene S determines the formation of curly hair, and its recessive allele t - straight hair. What kind of hair will the children have if the mother has light, straight hair, and the father has dark, curly hair (one of the pairs of traits is heterozygous for both parents)?
In humans, being right handed (R) is dominant over being left handed (r), and normal vision (X+) is dominant over color blindness (Xc). Color blindness is a X-linked (a.k.a sex linked) trait. Two right-handed parents with normal vision have a son who is color blind and left handed. What are the genotypes of the parents for right-handedness and color blindness?
In humans, "unattached" earlobes are dominant over "attached" earlobes. "Widows peak" hairline is dominant over "non-widows peak" hairline. Use E and e for the earlobe phenotype alleles, and W and w for the hairline phenotype alleles. A female and a male, both with genotype EeWw have a child. What is the probability it will be a boy, and have attached earlobes and a widows peak hairline?
Given a cross between these two parents: BbCcDDEEFfGgHhjj x BbCcddEeFfGgHHjj where traits B, E, H, J exhibit Mendelian inheritance; C, and F exhibit incomplete dominance; D, and G exhibit co-dominance answer the following: What proportion of the offspring will phenotypically resemble the first parent? What proportion of the offspring will genotypically resemble the second parent? How many phenotypes can be expected from the cross?
Phenotypic ratio: red : pink : white Solve the following genetic problems involving incomplete dominance. You must pick the right letter to represent the gene in the question. You must show your work using the Punnett square. 15. A rooster with grey feathers is mated with a hen of the same phenotype. Among their offspring 15 chicks are grey, 6 are black and 8 are white. a. What is the simplest explanation for the inheritance of these colors in chickens? b. What offspring would you expect from the mating of a grey rooster and a black hen?
Gregor Mendel discovered the basis of heredity with his sweet pea plant experiments. In his studies, he determined that certain traits, such as pod color and pea shape, express complete dominance. Trait Dominant Recessive Pod color Yellow Green Pea shape Round Wrinkled A cross occurs between a plant with heterozygous yellow pods and wrinkled peas and a plant with green pods and heterozygous round peas. What is the probability that the offspring will exhibit recessive genes for both traits? a) 1/2 b) 1/4 c) 1/8 d) 1/16
Seed color is controlled by 3 independently assorting bi-allelic genes (P, Q, R), such that homozygote pp exhibits recessive epistasis over the seed color pathway, converting a white pigment into yellow, which then becomes orange in the presence of a Q allele, or red in the presence of R. Individuals with both Q and R alleles show pink seeds. In a cross of PpQqRr individuals with ppqqrr individuals, what is the ratio of white-seeds to red seeds? а. 1:4 b. 2:3 с. 1:1 d. 4:1 e. 1:5
In earlobes, free (F) earlobe is dominant while attached (f) earlobe is recessive. What proportion of the offspirng would we expect to have attached earlobes in the following crosses: 1. Heterozygous dominant for ree earlobes with homozygous dominant for free earlobes. ______ 2. Homozygous dominant for free earlobes with attached earlobes. ______ 3. Attached earlobes with attached earlobes. (Answer in percent) ______
