When Mendel examined the inheritance of seed colour, he crossed true-breeding green and true-breeding yellow plants. All of the plants produced were yellow seeded. He then crossed the yellow-seeded plants and found that some of the offspring were green-seeded and some were yellow-seeded. What were the genotypes of the original parents? Yy and Yy yellow and green There is not enough information to tell. YY and yy green and Yy

The following pedigree shows the pattern of inheritance of red-green color blindness in a family. Females are shown as circles and males as squares; the squares or circles of individuals affected by the trait are filled in black. What is the chance that a son of the third-generation female indicated by the arrow will be color blind if the father is not color blind? If he is color blind?
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?
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.
Over the years, Mendel experimented with more than 30,000 pea plants. Why did Mendel collect data on so many plants? Why didn’t he study just one cross? Hint: Read “What Are the Odds?” on page 124 before answering.
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
In pea plants, smooth peas is dominant to wrinkled peas. When Mendel crossed true breeding smooth peas with true breeding wrinkled peas, what is the genotype of the offspring and what percentage?
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?
When Mendel was conducting his research, he crossed two different varieties of pea plants, one that had jagged leaves with 8 points on each leaf and one that had perfectly smooth leaves. He found that the offspring all had 4 to 5 points on each leaf. Based on what you have learned in this course, how would you explain this result to Mendel?
If mendel crossed heterozygous smooth pea plants with each other, what would be the genotype and phenotype ratio of the offspring?
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?
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 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?
