Breaking Down Standards Worksheet L.8.2A Students will demonstrate an understanding of how sexual reproduction results in offspring with genetic variation while asexual reproduction results in offspring with identical genetic information. L.8.2C Students will demonstrate an understanding that chromosomes contain many distinct genes and that each gene holds the instructions for the production of a specific protein, which in turn affects the traits of an individual.

Sexual Reproduction identical copy but there is little asexual or sexual reproduction Asexual Reproduction genetic diversity unless there is * Identify Identical a mutation. advantages/disadvantages of Genetic * Sexual reproduction takes each type of reproduction. Diversity longer (meiosis, fertilization, Disease Resistance growth and development) and Undesirable creates a unique individual, greater genetic diversity.
