Lecture 2.8 Competencies and Study Guide
Hardy-Weinberg
Vocabulary
- SINE (Short interspersed element)
- Transposable element
- Allele frequency
- Genotype frequency
Competencies
- Describe the Alu insertion in primate.
- State what proportion of the human genome is the Alu insertion.
- Calculate the allele frequencies from genetic data for single-gene, simple traits like the PV92, tPA25 and ACE-I Alu insertions.
- State the 5 Hardy-Weinberg assumptions.
- Calculate the expected genotype frequencies of a population in the next generation given current genotype frequencies assuming the population is in Hardy-Weinberg equilibrium.
- State the Hardy-Weinberg theorem for the single gene, 2-allele case.
- Explain why populations that fit the Hardy-Weinberg assumptions do not evolve, and why, therefore, evolution is expected to be very common.
- State and explain all mechanisms of evolution, and relate them to violations of the Hardy-Weinberg assumptions.
- Determine, using the Hardy-Weinberg theorem, if traits are evolving given genetic data from a population; be able to solve this problem using tPA25 and ACE-I data from northern Italy as examples.
