Students will learn what genetics is and what is going to be interesting and fun about the chapter.
Students will be introduced to Chapter 11, Genetics.

Anticipatory Set: * Students will look at five different pictures of horses. Then they will discuss what is different about the horses. Students will then take a piece of scratch paper and draw a table with horse names on left and five characteristics on the top. Students will then describe each of those characteristics of each of the horses. Students will describe the characteristics they listed to the teacher as the teacher list them for the students.
