Lesson 2 The Theory of Evolution by Natural Selection – We learned that in addition to variations that arise from sexual reproduction, genetic information can be altered because of mutations. Though rare, mutations may result in changes to the structure and function of proteins. Some changes are beneficial, others harmful, and some neutral to the organism.

Test on Lesson 1 How Traits Change.

Lesson 1 How Traits Change – We reviewed for a test on Lesson 1. We added notes on mutations and genetic disorders.

We worked on simplifying algebraic equations and combining like terms.

Lesson 1 How Traits Change – We reviewed that genes are located in the chromosomes of cells, with each chromosome pair containing two variants of each of many distinct genes. Each distinct gene chiefly controls the production of specific proteins, which in turn affects the traits of the individual.
Assignment: Add pictures of chromosomes, genes, proteins, and traits to science notebook.

Lesson 1 How Traits Change – We learned that changes (mutations) to genes can result in changes to proteins, which can affect the structures and functions of the organism and thereby change traits. Each chromosome consists of a single very long DNA molecule and each gene on the chromosome is a particular segment of that DNA. Instructions for forming species’ characteristics are carried in DNA. All cells in an organism have the same genetic content but the genes used or expressed by the cell may be regulated in different ways.
