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.
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?
Variations on a Theme by Mendel A characteristic of snapdragons amenable to genetic analysis is flower color. Imagine that a true-breeding red- flowered variety is crossed to a pure line having white flowers. The progeny are exclusively pink-flowered. Diagram this cross, including genotypes for all P1 and F1 phenotypes. What is the mode of inheritance? Let F = red and f = white.
Mendel crossed peas having round seeds and yellow cotyledons with peas having wrinkled seeds and green cotyledons. All the F1 plants had round seeds with yellow cotyledons. Diagram this cross through the F2 generation, using both the Punnett square and forked-line methods.
Mendel crossed two Pea plants for plant height and flower color Tall plant (T) is dominant to Short Plant (t). Purple Flower (P) is dominant to white flower (p). Using the following information perform the dihybrid cross using punnett squares that will predict all possible genotypes of the offspring and list the number and description of the phenotypes of the offspring. A. One plant homozygous dominant for plant height and flower color crossed with another plant homozygous recessive for plant height and heterozygous for flower color.
Mendel crossed peas having round seeds and yellow cotyledons (seed leaves) with peas having wrinkled seeds and green cotyledons. All the F1 plants had round seeds with yellow cotyledons. Diagram this cross through the F2 generation, using both the Punnett square and forked-line, or branch diagram, methods.
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 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 breading pea plant with yellow pods. Assuming that green is the dominant color indicate the genotype of the parents and the phenotypic ratio of F2 generation.
In Mendel’s 1866 publication as shown in Figure 1-4,he reports 705 purple-flowered (violet) offspring and224 white-flowered offspring. The ratio he obtained is3.15:1 for purple: white. How do you think he explainedthe fact that the ratio is not exactly 3:1?
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?
Mendel describes subjecting each of the 34 varieties of peas he obtained to a two-year trial. During this time he let the plants self-fertilize and observed their offspring. What was he looking for, and what was the purpose of doing this two-year trial? 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
