For a hypothetical budding yeast trait, C is dominant to c, so C_ produces the knotted phenotype and cc produces the webbed phenotype. However, CC is lethal and those offspring do not survive.

Parent 1: Cc × Parent 2: Cc.
Of the offspring that survive, what fraction will have the knotted phenotype?

None, 0% Incorrect 1/4, 25% Incorrect 1/3, 33.3% Incorrect 2/3, 66.7% Correct All, 100% Incorrect MC

Genotype	Outcome
CC	Lethal, does not survive
Cc	Dewy
cc	Spicy

For a hypothetical fruit fly trait, C is dominant to c, so C_ produces the dewy phenotype and cc produces the spicy phenotype. However, CC is lethal and those offspring do not survive.

Parent 1: Cc × Parent 2: Cc.
The cross produces 96 surviving offspring.
How many of the surviving offspring do you expect to have the spicy phenotype?

0 × 96 = 0 offspring Incorrect 1/3 × 96 = 32 offspring Correct 1/2 × 96 = 48 offspring Incorrect 2/3 × 96 = 64 offspring Incorrect 1 × 96 = 96 offspring Incorrect MC

CC	Lethal, does not survive
Cc	Bubbly
cc	Clumpy

For a hypothetical budding yeast trait, C is dominant to c, so C_ produces the bubbly phenotype and cc produces the clumpy phenotype. However, CC is lethal and those offspring do not survive.

Parent 1: Cc × Parent 2: Cc.
Before considering survival, assume the cross produces 72 offspring.
How many would you expect to have the lethal CC genotype?

0 × 72 = 0 offspring Incorrect 1/4 × 72 = 18 offspring Correct 1/3 × 72 = 24 offspring Incorrect 2/3 × 72 = 48 offspring Incorrect 3/4 × 72 = 54 offspring Incorrect MC

Genotype	Outcome
CC	Lethal, does not survive
Cc	Bumpy
cc	Chummy

For a hypothetical fruit fly trait, C is dominant to c, so C_ produces the bumpy phenotype and cc produces the chummy phenotype. However, CC is lethal and those offspring do not survive.

Parent 1: Cc × Parent 2: Cc.
The cross produces 120 surviving offspring.
How many of the surviving offspring do you expect to have the chummy phenotype?

0 × 120 = 0 offspring Incorrect 1/4 × 120 = 30 offspring Incorrect 1/3 × 120 = 40 offspring Correct 2/3 × 120 = 80 offspring Incorrect 1 × 120 = 120 offspring Incorrect MC

Genotype	Outcome
CC	Lethal, does not survive
Cc	Stringy
cc	Doubled

For a hypothetical budding yeast trait, C is dominant to c, so C_ produces the stringy phenotype and cc produces the doubled phenotype. However, CC is lethal and those offspring do not survive.

Parent 1: Cc × Parent 2: cc.
What ratio do you expect among the offspring that survive?
stringy : doubled
