✅ 5 short answer questions to develop critical thinking and explanatory skills
✅ PDF worksheet and PDF answer key with rubric included for easy grading and distribution
(Note: No digital forms or editable files are provided)
Key Concepts Covered
➡️ Genetic drift – The random fluctuation of allele frequencies in a population over time
➡️ Population bottleneck – An event that drastically reduces genetic diversity due to environmental or other factors
➡️ Founder effect – The reduced genetic variation when a new population is started from a small number of individuals
➡️ Allele frequency changes – How chance events influence the genetic makeup of populations
➡️ Evolutionary mechanisms – Processes that cause change in the genetic composition of populations, including genetic drift
