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.
