Population Modeling

The video tutorial introduces population modeling, starting with the concept of populations and individuals using oak trees as an example. It explains the human lifecycle in biological terms and introduces the concept of a gene pool. The tutorial discusses the Hardy-Weinberg equilibrium and its five rules. It then demonstrates how to use spreadsheets for population modeling, focusing on allele frequencies and genetic drift. The video concludes with an experiment on genetic drift, showing how small population sizes can lead to random changes in allele frequencies.

What is the initial stage of an oak tree's life cycle?

• Seedling

• Acorn

• Sapling

• Leaf

In the human lifecycle model, what do adults produce?

• Juveniles

• Gametes
