In snapdragons, the combined expression of both alleles for flower color produces a new phenotype that is pink. This illustrates incomplete dominance. The Punnett square above shows that both the white and red snapdragons are homozygous. Which of the following would be correct product from a cross between two heterozygous pink snapdragons?

• 2 red, 1 pink, 1 white

• 1 red, 2 pink, 1 white

• 1 red, 1 pink, 2 white

• 2 red, 2 white

In a pond, the primary producer is a green alga, Spirogyra; the primary consumer is the crustacean, Daphnia; the secondary consumer is a small fish, the bluegill; and the tertiary consumer is a larger fish, the smallmouth bass. What changes can be expected in the pond if the Daphnia are killed with pesticides?

• The Spirogyra population will probably die.

• The bluegill population will probably increase.

• The Daphnia population will eat something else.

• The smallmouth bass population will die.

Rabbits introduced into Australia over 100 years ago have become a serious pest to farmers. Rabbit populations increased so much that they displaced many native species of plant eaters. What is the most logical explanation for their increased numbers?

• Rabbits have a high death rate.

• There are few effective predators.

• Additional rabbit species have been introduced.

• There is an increase in rabbit competitors.

• mutation rate

• natural selection

• genetic variation

A single species of squirrel evolved over time into two species, each on opposite sides of the Grand Canyon. This change was most likely due to

• higher mutation rates on one side.

• low genetic diversity in the initial population.

• the isolation of the two groups.

• differences in reproductive rates.

The diagram shows undisturbed sedimentary strata at the bottom of an ocean. The fossils found in layer B resemble the fossils found in layer A. This similarity suggests that

• modern forms of life may have evolved from earlier forms of life

• vertebrate fossils the fossils in layer B were formed before the fossils in layer A

• fossils are only found in sediments

• the fossils in layer A must be more complex than those in layer B
