Unit 2 Lesson 1 Quiz: Inheritance and Reproduction

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? Circle the letter of the correct answer.

• Smooth shape and wrinkled shape are both recessive traits.

• Smooth shape and wrinkled shape are both dominant traits.

• Smooth shape is a dominant trait, and wrinkled shape is a recessive trait.

• Smooth shape is a recessive trait, and wrinkled shape is a dominant trait.

Eye color is a gene that is passed down from father and mother to child. Brown eye color is a dominant trait, and blue eye color is a recessive trait. If a father has brown eyes (Bb) and a mother has blue eyes (bb), what is the probability that their child will have blue eyes? Write the correct letter in each box to correctly complete the Punnett square in your notebook and in the blank in the conclusion text under the Punnett square.

A student observing a population of bacteria has determined that the generation time is 15 minutes. Starting with a single bacterium, graph the growth of the population over a period of 75 minutes. Use your pencil to graph the growth of the bacteria population every 15 minutes starting with 1 cell at time 0 and ending at 75 minutes.
