Across
- 3. One means to create variance related to natural selection
- 6. Average trait favored
- 7. Can interbreed and live in the same area
- 11. An individual's set of alleles that determines the phenotype
- 13. Another word for disruptive selection
- 14. The group of genes within a population
- 18. Male reproduction is limited by their access to females
- 19. A few individuals become separated from their population to start a new subpopulation
- 20. Chromosomal or gene
Down
- 1. Observable features
- 2. A sudden flood majorly decreases the population size and the resulting population has far less genetic diversity
- 4. Creates variance via crossing over and independent assortment
- 5. Species adopt traits to make them more desirable for mating
- 8. Selection across generations
- 9. Ability to survive and propagate genes
- 10. Different forms of a gene
- 12. A change in the relative frequency of alleles in the gene pool
- 14. One way to create variance not related to natural selection
- 15. Migration can introduce different alleles to populations
- 16. More extreme form of a trait favored
- 17. How frequently a particular allele occurs in a gene pool
