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.
