11.2 Applying Mendel's Principles

When you flip a coin, what is the probability that it will come up tails?

• 1

• 1/2

• 1/4

• 1/8

The principles of probability can be used to

• predict the traits of the offspring of genetic crosses.

• determine the actual outcomes of genetic crosses.

• determine which species should be used in genetic crosses.

• decide which organisms are best to use in genetic crosses.
