Objectives: By the end of this unit you should be able to: Name and describe the steps of mitosis Name and describe the steps of meiosis Set up and complete Punnett squares Read a pedigree Describe the structure and function of DNA Compare and contrast DNA and RNA Explain the relationship between phenotypes and genotypes Explain how genetic mutations may occur Describe how genetic variations can increase the probability of survival Continue to perform accurate measurements and follow proper laboratory procedures NGSS:
MS-LS1-3.Use argument supported by evidence for how the body is a system of interacting subsystems composed of groups of cells. MS-LS3-1.Develop and use a model to describe why structural changes to genes (mutations) located on chromosomes may affect proteins and may result in harmful, beneficial, or neutral effects to the structure and function of the organism. MS-LS3-2.Develop and use a model to describe why asexual reproduction results in offspring with identical genetic information and sexual reproduction results in offspring with genetic variation. MS-LS4-3.Analyze displays of pictorial data to compare patterns of similarities in the embryological development across multiple species to identify relationships not evident in the fully formed anatomy. MS-LS4-4.Construct an explanation based on evidence that describes how genetic variations of traits in a population increase some individuals’ probability of surviving and reproducing in a specific environment. MS-LS4-5.Gather and synthesize information about the technologies that have changed the way humans influence the inheritance of desired traits in organisms. MS-LS4-6.Use mathematical representations to support explanations of how natural selection may lead to increases and decreases of specific traits in populations over time.
