Description

Summative unit assessment covering heredity and genetics: inherited vs. acquired traits, DNA/chromosomes/genes, alleles and dominance, genotype vs. phenotype, Punnett squares, sexual vs. asexual reproduction, genetic variation and survival, and environmental effects on gene expression.

Learning Objectives

  • Distinguish between inherited and acquired traits and explain the relationship between DNA, chromosomes, and genes

  • Define alleles, distinguish dominant from recessive, and explain the difference between genotype and phenotype

  • Use Punnett squares to predict offspring trait probabilities

  • Compare sexual and asexual reproduction and explain why genetic variation is important for species survival

  • Describe how environment and lifestyle can affect gene expression and distinguish heritable mutations from non-heritable changes

Standards Alignment

7.L.2
Understand the relationship between genetics and heredity, including how traits are passed from parent to offspring
7.L.2.1
Explain why offspring that result from sexual reproduction have greater variation than offspring from asexual reproduction
