I can determine the effect of Genetic Drift on populations

LTLT:  I can develop, communicate, and justify an evidence-based explanation for the evolution of organisms and environments by analyzing and interpreting data from the fossil record. LT: I can determine the effect of Genetic Drift on populations. Criteria for Success: *I can complete a lab with a new species: Frootloopitus cerealis * I can count fruit loops into new populations Agenda: Warm UP LT & C.S. Genetic Drift is…. Fruit Loop Lab Questions

   Debrief 

  Warm UP: 

What’s the difference between genes and jeans??

Review LTLT, LT & C.S.

Genetic Drift is….                     

*A change in DNA in a population, due to a random event. This has to do with luck, not fitness.

Founder Effect Event…

*Occurs when a new colony is started by a few members of the original population

Bottleneck Event…. 

*When a population’s size is reduced for at least one generation. 

Fruit Loop Lab:

Scientists have just discovered a NEW species, called: frootloopitus cerealis

You are going to do a lab where you explore the idea of Genetic Drift with populations of this new species.

Lab Questions

Debrief/Exit Ticket

Q1: Based on the fruit loop lab, what is Genetic Drift?

Q2: What does Genetic Drift have to do with populations?
