When Mendel crossed violet-flowered peas with white-flowered peas, the first generation all had pale violet, blended flowers.
Which plant did Gregor Mendel use for his famous experiments on inheritance?
In an Aa × Aa cross with complete dominance, what percentage of offspring are expected to show the recessive phenotype?
Two parents with blue eyes can never have a child with brown eyes.
Two heterozygous parents (Aa × Aa) are crossed. What genotype ratio does a Punnett square predict for the offspring?
A round-seeded pea plant of unknown genotype is crossed with a wrinkled (rr) plant. About half the offspring are wrinkled. What was the unknown genotype?
Mendel counted 705 violet-flowered and 224 white-flowered F2 plants. What is the ratio of violet to white, to two decimal places?
Pink snapdragons (heterozygotes for flower colour) are self-crossed. Which outcome shows incomplete dominance?
State Mendel's law of segregation and identify the event in meiosis that is its physical basis.
Two genes sit very close together on the same chromosome. Explain why a cross between double heterozygotes may not give Mendel's 9:3:3:1 ratio, and what process can make such genes behave as if unlinked.
