Developing and Using Models
Cause and Effect: Cause and effect relationships may be used to predict phenomena in natural systems.
This lesson is a detailed explanation of the backcross breeding process. Variations based on whether backcrossing is performed with dominant, recessive, or multiple traits are discussed. Calculations associated with backcross breeding are explained.
