Dihybrid Crosses and EOC Review

An experiment is being done to determine how light affects the growth of small zinnia plants. One plant is placed in full sunlight, the second in a shaded area, the third in an unlit closet. What is the independent variable in the experiment?

A scientist investigates the effect of carbon dioxide on plant height. The scientist grows plants in several closed containers. All the plants receive the same amounts of water and light, but the air in each container has a different amount of carbon dioxide. What is the independent variable in this experiment?

• the amount of carbon dioxide in each container

• the number of plants in each container

• the amount of water provided to the plants

• the height of each plant after a period of time

A white mouse with red eyes is crossed with a black mouse with brown eyes. The white mouse is recessive for both of its traits. The black mouse is dominant for both of its traits.

This cross would be

• BBEE x bbee

• BBEe x BbEe

• BbEE x BbEe

• BBee x BBEE
