Ever wonder how biologists reconstruct ancient human migrations?  Or, how a paternity test works? It’s all in the genes, folks!  Our session will focus on the many practical applications of molecular biology. Building on the Lady Beetle Blitz session, we’ll describe variation in field collected beetles, categorizing them based on phenotype, and then use molecular tools to reconstruct their North American Invasion in the late 1980s.

At the conclusion of the lesson, students will be able to:

  • Describe the diversity of a population in terms of phenotype and genotype.
  • Use genotypic information to answer questions about the migration of a species.
  • Use genotypic information to answer evolutionary questions about organisms.
