Figure 8.10 In pea plants, purple flowers (P) are dominant to white (p), and yellow peas (Y) are dominant to green (y). What are the possible genotypes and phenotypes for a cross between PpYY and ppYy pea plants? How many squares would you need to complete a Punnett square analysis of this cross?
When Gregor Mendel performed his breeding experiments on pea plants, he discovered that tallness in the plants is inherited through a simple dominant trait (coded "T") with shortness as the recessive trait (coded "t"). Imagine that Mendel bred a homozygous dominant pea plant with a pea plant heterozygous for tallness. Draw a Punnett Square to help you answer this question and the next one: In the 1st generation of offspring, we expect the phenotypes (for tallness) to include… a) 50% homozygous dominant, 50% heterozygous b) 100% heterozygous c) 50% tall, 50% short d) 100% tall e) None of the above
In oats, the color of the chaff is determined by a two-gene interaction. When a true-breeding black chaff plant was crossed to a truebreeding white chaff plant, the F1 generation was composed of allblack chaff plants. When the F1 offspring were crossed to eachother, the ratio produced was 12 black to 3 gray to 1 white. First,construct a Punnett square that accounts for this pattern of inheritance. Which genotypes produce the gray chaff phenotype? Second,at the level of protein function, how would you explain this type ofinheritance?

In the clover butterfly, males are always yellow, but females can beyellow or white. In females, white is a dominant allele. Two yellow butterflies were crossed to yield an F1 generation consisting of50% yellow males, 25% yellow females, and 25% white females.Describe how this trait is inherited and specify the genotypes ofthe yellow parents.
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: How many phenotypes can be expected from the cross?
In Figure 1-6, the students have 1 of 15 different heights,plus there are two height classes (4′11″ and 5′ 0″) forwhich there are no observed students. That is a total of17 height classes. If a single Mendelian gene can account for only two classes of a trait (such as purple orwhite flowers), how many Mendelian genes would beminimally required to explain the observation of 17height classes?
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?

If you are working to solve for the relative distances between a cat's genes for fur color, where gene X has alleles X and x and gene Y has alleles Y and y that follow an autosomal dominant pattern of inheritance, which test-cross should you perform to determine a genetic map? A. XxYy x XxYy B. XXYY x xxyy C. XxYy x xxYy D. XxYy x xxyy
In one study, Gregor Mendel crossed yellow-seeded, tall garden pea with a green-seeded,short garden pea. The F1 offspring were all yellow-seeded and tall. Assumingindependent assortment of these two genes, what phenotypes and proportions did he finamong F2 offspring when the F1 garden peas are allowed to fertilize themselves? Show the solution with punnett square.
In rabbits, black hair is due to a dominant allele B and brown hair to its recessive allele b. Short hair (H) is dominant to long hair (h). Show punnet squares In a cross between a homozygous black, longhaired rabbit and a brown, homozygous shorthaired one, what would the F1 generation look like? If you did not know the genotype of an F1 rabbit, you could determine its genotype by a test cross in which it is crossed with an animal with which phenotype AND genotype? If you carried out this test cross (from 2, using the F1 from 1), what phenotypes and in what ratio would you expect? What phenotypes in what ratio would be expected in the F2 generation of the cross in point 1?
