Unit 8 Genetics

Genetics Standards / Objectives

Bio.3.1 Explain how traits are determined by structure and function of DNA

Bio.3.1.3 Explain how mutations in DNA that result from interactions with the environment (ex. radiation and chemicals) or new combinations in existing genes lead to changes in function and phenotype

Bio.3.2 Understand how the environment, and/or the interaction of alleles, influences the expression of genetic traits

Bio.3.2.1 Explain the role of meiosis in sexual reproduction and genetic variation

• • Infer the importance of genes being on separate chromosomes as it relates to meiosis

  • Explain how the process of meiosis leads to independent assortment and genetic diversity

Bio.3.2.2 Predict offspring ratios based on a variety of inheritance patterns (including: dominance, co-dominance, incomplete dominance, multiple alleles, and sex-linked traits)

Bio.3.2.3 Explain how the environment can influence the expression of genetic traits
