  1. Do Now 3.5 Week 27 Objectives: Define polygenic trait and pleiotropy. Review chromosomes and cell division Task: Pass forward the FLYLABS! And last week’s Do Nows. A banana plant is 3n = 33. How many different types of chromosomes are present in each cell?

  2. Polygenic Trait: A trait controlled by multiple genes • Traits which display a large variation or range of phenotypes are often polygenic. Human skin tone, for example is controlled by 6 different genes

  3. Pleiotropy: One gene produces many different effects or phenotypes

  4. Review Part I: Chromosomes And Cell Division • Terminology trading: • Your group has been assigned a number of terms. During your turn, you select one to define. • If you are right, you may select one term to trade to the next group. • If you are wrong, you keep that word and do not get to trade. • The winning team is the team that defines all of its words first.
