Mendel performs a cross using a true-breeding pea plant with round, yellow seeds and a true- breeding pea plant with green, wrinkled seeds. What is the probability that offspring will have green, round seeds? Calculate the probability for the F1 and F2 generations.
When Mendel crossed yellow-seeded and green-seeded pea plants, all the offspring were yellow-seeded. When he took these F1 yellow-seeded plants and crossed them to green-seeded plants, what genotypic ratio was expected? What is the name of this type of cross?
Mendel used dihybrid crosses to test the idea that alleles for two different characters assort independently. In a typical dihybrid cross (such as RrTt x RrTt), what proportions of phenotypes would be expected in the offspring? Select one: a. 9:3:3:1 b. 4:4:4:4 c. 2:2 d. 3:1 e. 100% dominant phenotype

In Mendel’s 1866 publication as shown in Figure 1-4, he reports 705 purple-flowered (violet) offspring and 224 white-flowered offspring. The ratio he obtained is 3.15:1 for purple: white. How do you think he explained the fact that the ratio is not exactly 3:1?
Why did Mendel perform "reciprocal crosses"? Someone gives you a bag of yellow peas and you plant them in the Spring. Can you predict the color of the peas that will appear in the pods on the plants grown from these peas? Would your answer be different if you had received a bag of green peas? Explain what Mendel means when he writes that the 3:1 ratio observed in the first generation from the hybrids "resolves itself" into a ratio of 2:1:1
Mendel crossed a true-breeding pea plant with green pods and a true-breeding pea plant with yellow pods. All the F1 plants had green pods. Which color is recessive?
There are 25 offspring from a cross of AaBb x AaBb. If Mendelian ratios are followed, how many offspring would you expect to have recessive phenotypes for both traits?
Use a branch diagram to determine all the phenotypes and corresponding ratios that are expected to occur among the offspring of the following Mendelian cross; d d E e F f X D D e e Ff. Assume incomplete dominance for D, E and F. Hint: are phenotypes and genotypes the same or different in this case?

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.
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?
