Unit Overview / Details

This unit contains lessons on genes, genetic characteristics, phenotype and genotype ratios, cell division and fertilization processes.

Instructional Hours

15 Hours

Content / Concepts

  • Genotypes and phenotypes and how dominant and recessive genes function
  • Comparing genetic characteristics among cattle, sheep, swine, and horse breeds
  • How to display phenotype and genotype ratios (e.g. using a Punnett Square)
  • The fertilization process
  • Purpose and processes of mitosis and meiosis

  • This lesson will cover the principles of dominant and recessive traits, using Punnett Squares; specifically monohybrid crosses. Prior to this lesson students should already have covered curriculum in genotype and phenotype.

    Dominant & Recessive Traits
    20 Minutes
    Punnett Squares
    40 Minutes
  • This is a follow-up lesson to a basic mutation lesson.  At the end of the lesson students will be able to describe how some genetic mutations are not advantageous, they will differentiate why some species survive while others become extict, and will describe how changes in the environment determine wether or not a genetic change is beneficial.
