Agenda Bell Work Lesson of the Day- -C4 Levels of Genetic Info -Cracking the code of Life DVD

Objective Explain the growth and repair of a multicellular organism in terms of mitosis. Identify and describe the homozygous and heterozygous expression of traits. Demonstrate an understanding of the probability that a particular trait is passed on to an offspring through genetic recombining. Compare and contrast the purpose for and results of mitosis and meiosis.

Objective in Layman’s When do we see Mitosis vs. Meiosis ? When do we see Mitosis vs. Meiosis ? Why do Cells Divide? Why do Cells Divide? How can we use Division to help us? How can we use Division to help us? When can it hurt us? When can it hurt us?

Information Life is sometimes a game of chance.

Today’s Lesson Looking at Traits, we know that they are controlled by Genes. Genes are Segments of DNA that control for a Trait (Protein)
