Read each question. Circle the letter of the correct answer.
1. Look at the diagram shown.
4. A botanist crosses a pea plant that produces
smooth seeds with a pea plant that produces
wrinkled seeds. The resulting plants all
produce smooth seeds. What can be determined
from the results of the experiment?
A. Smooth shape and wrinkled shape are both
recessive traits.
B. Smooth shape and wrinkled shape are both
dominant traits.
C. Smooth shape is a dominant trait, and
wrinkled shape is a recessive trait.
D. Smooth shape is a recessive trait, and
wrinkled shape is a dominant trait.
Which of these gives the correct ratio for the
offspring predicted by the diagram?
5. The diagram shows several structures located
within a cell.
A. 2 BB : 1 Bb
B. 1 BB : 1 BB
C. 1 BB : 1 Bb
D. 1 BB : 2 Bb
2. Alleles carry the codes for producing which of
these types of large molecules?
A. lipids
B. proteins
C. nucleic acids
D. carbohydrates
Which statement best describes the relationship
among the structures?
3. A scientist crossed a white-flowered plant with
a blue-flowered plant. Which of these
outcomes would show that blue flower color is
dominant to white flower color?
A. Structures B and C are located IN Structure
A and code for inherited traits.
B. Structures B and C come together to form a
new organisms during fertilization.
A. All of the second generation is blue.
C. Structure A is a small part of Structures C
and B, and codes for a single inherited trait.
B. All of the second generation is white.
C. One-fourth of the second generation is blue.
D. Structure C is located within Structure B,
which is located within Structure A, and all
three code for different versions of the same
trait.
D. One-fourth of the second generation is white.

Read each statement. Write your answer on the lines.
8. Jake made a chart to trace the traits of straight and curly hair in his family.
The lines on the chart show relationships. Parents are connected by a horizontal line while vertical lines
lead to their offspring. A shaded circle or square in Jake’s chart represents a person with straight hair.
Predict if the straight hair is controlled by a dominant allele or a recessive allele? (Hint – If straight
hair is a dominant allele , it should be present in ALL generations of the family)
9. A pair of fruit flies reproduces and has one thousand offspring. All one thousand of the offspring have
the alleles gg. What is the most likely combination of alleles for each parent?

10. The diagram shows a Punnett square made to predict the earlobe shape of the offspring of two parents.
The capital A stands for the trait of free-hanging earlobes, and the lowercase a stands for the trait of
attached earlobes.
Write the genotype of each offspring.
What will be the phenotype of each offspring?
Is the trait of free-hanging earlobes dominant or recessive?
What is the expected ratio of free-hanging earlobes to attached earlobes in the offspring?
