Gene P has three possible alleles, or gene forms, called a, b and c. Each individual carries two copies of Gene P, one of which is inherited from his or her mother and the other of which is inherited from his or her father. If the two copies of Gene P are of the same form, the individual is homozygous for that allele; otherwise, the individual is heterozygous. The following table represents genetic data from 500 individuals selected at random from the population. Allele 2abcAllele 1a61039b112179c3665233Using experimental probability, predict the number of individuals in a population of 100,000 who will be homozygous for either the a or b allele.

The Praxis Mathematics (5165 ) Exam is a test required by many states for credential candidates planning to teach mathematics at the high school level. It is a single, computer-delivered test that includes questions from two content categories.

The first content category includes Number and Quantity, Algebra, Functions and Calculus. The second content category includes Geometry, Probability and Statistics, and Discrete Mathematics.

The test consists of various question types including selected-response, numeric entry, drag-and-drop and text completion.
