Genetics

Standards:

LS.3.A.1-Develop and use models to clarify relationships about how DNA in the form of chromosomes is passed from parents to offspring through the processes of meiosis and fertilization in sexual reproduction.

LS.3.B.2-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.

LS.3.B.3-Make and defend a claim that inheritable genetic variations may result from: (1) new genetic combinations through meiosis, (2) mutations occurring during replication, and/or (3) mutations caused by environmental factors.

LS.3.B.4-Apply concepts of statistics and probability to explain the variation and distribution of expressed traits in a population.

LS.4.B.2-Apply concepts of statistics and probability to support explanations that organisms with an advantageous heritable trait tend to increase in proportion to organisms lacking this trait.

LS.3.B.1-Compare and contrast asexual and sexual reproduction with regard to genetic information and variation in offspring
