From this crossword puzzle, students will: (1) define gene pool; (2) describe how allele frequencies are related to gene pools; (3) state in genetic terms, what indicates that evolution is occurring in a population; (4) describe two processes that can lead to inherited variation in populations; (5) distinguish between single-gene traits and polygenic traits; (6) define fitness, adaptation, survival of the fittest, and natural selection; (7) describe how natural selection can affect single-gene traits; (8) describe three patterns of natural selection on polygenic traits; (9) define genetic drift, founder effect, and mutation; and (10) relate concepts to the Hardy-Weinberg principle.
Words used include: population, gene pool, relative frequency, evolution, mutation, independent assortment, crossing-over, single-gene trait, polygenic trait, fitness, adaptation, natural selection, directional selection, stabilizing selection, disruptive selection, genetic drift, founder effect, Hardy-Weinberg principle, and genetic equilibrium. These words are listed in the second spreadsheet, but you can delete them if desired.
