Mendel finds a new species of pea plant that produces two different flower colors, white and blue, based off of a single gene with two alleles. He crosses together two parents, a true-breeding white and a true- breeding blue flowered plant. All of the plants in the F1 generation have blue flowers. Two of the F1 offspring are mated. What proportion of the blue F2 offspring is expected to be homozygous? O2/3 O1/2 1/3 1/4

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.
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?
Mendel found that three traits in peas—height, flower color, and pod shape—are determined by different genes, and that these genes assort independently. Suppose that true-bred tall plants with violet flowers and inflated pods are crossed to true-bred dwarf plants with white flower and constricted pods. All the plants in the F1 generation are tall, with violet flowers and inflated pods. If these F1 plants are self-fertilized, what fraction of their offspring are expected to … a.)show all three dominant phenotypes? b.)be tall with white flowers and constricted pods?
If Gregor Mendel crossed a true breeding round pea plant seed with a true breeding wrinkled pea plant seed, and the F1 were all round, what percentage of the F2 generation would likely be wrinkled? Question 2 options: 25 % 30 % 50% 75 %
Mendel performed crosses in which he used pollen from a white-flowered plant to fertilize a purple-flowered plant and pollen from a purple-flowered plant to fertilize a white-flowered plant, showing the same results with both. What did these reciprocal crosses demonstrate? A. That the plants were not sterile. B. That there was no epistasis. C. That the trait could be passed from either parent. D. B and C.
When Mendel crossed in his P generation a yellow-seeded and green-seeded pea plants, all the offspring were yellow seeded. When he took these F1 yellow-seeded plants and crossed them with the original yellow-seeded plant from the P generation, what genotypic ratio was expected? Group of answer choices 1:2:1 3:1 1:1:1:1 1:1
Mendel also studied tall and short varieties of pea plants. When he crossed tall x short plants together, the F1were tall. The tall F1 plants were self-hybridized to produce the F2. What proportion of phenotypes would be expected in the F2? 1:2:1 tall:intermediate:short 3:1 tall:short 1:1 tall:short 3:1 short:tall 1:2:1 intermediate:tall:short
Mendel crossed homozygous plants with green seeds with homozygous plants with yellow seeds and found what all offspring were yellow construct a genetic diagram to show f1 and f2 generation
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 crossed peas having round green seeds with peas havingwrinkled yellow seeds. All F1 plants had seeds that were roundand yellow.
If mendel crossed heterozygous smooth pea plants with each other, what would be the genotype and phenotype ratio of the offspring?
