Different

Same

Exact

Equal

50%

12.

A scientist recently found an invertebrate species living in the deep sea that had never been identified previously. The scientist wants to determine if the species reproduces sexually. Which of the following investigations will help her answer the question?

a)

Genes

b)

DNA

c)

Sexual reproduction

d)

Asexual reproduction

13.

What can one predict from the results of the Punnett square?

a)

60%

b)

700%

c)

50%

d)

76%

14.

During the 1800s, Gregor Mendel conducted experiments with pea plants. His work showed that organisms inherit traits from their parents and that some traits are dominant over others. Mendel's work was ignored for a long time because scientists could not explain how traits were carried from one generation to the next. What discovery provided scientists with a way to explain Mendel's work?

a)

Punnett Square

b)

Punnett

c)

Square

a)

Sexual- asexual reporudction

a)

None

b)

All

c)

c)

25%

d)

75%

18.
