ESSENTIAL KNOWLEDGE: VARIATION IN TRAITS

Within this section, the learner will:

  • Understand how traits vary in Mendelian genetics due to incomplete dominance, and codominance
  • Learn the process of mutation and how it changes an organism’s genetic makeup
  • Be able to identify the difference between genetic and environmental variation in traits
