Across
- 4. (Two words.) The differential success (survival and reproduction) of individuals within a population
- 7. (Two words.) The movement of genetic information among populations
- 9. (Two words.) A change in allele frequencies (may also change genotype frequencies) because of random chance
- 13. A population adapted to its unique local environmental conditions
- 16. (Two words.) The ability of one genotype to give rise to different phenotypes under different environmental conditions
- 18. Individuals mate with other members of the population who are more closely related to them than expected by random chance
- 20. Any heritable behavioral, morphological, or physiological trait that has evolved through the process of natural selection such that it maintains or increases the fitness of an organism under a given set of environmental conditions
- 21. (Two words.) The sum of all genetic information (all alleles) across all individuals in a population
Down
- 1. Alternative forms of the same gene
- 2. Encodes the information needed to produce an RNA molecule
- 3. The proportionate contribution made by an individual to future generations relative to other individuals in the same population
- 5. (Two words.) Individuals in a population choose mates based on their phenotype, which reflects their genotype
- 6. Changes in a population of organisms over time
- 8. (Three words.) The set of phenotypes expressed by a single genotype across a range of environmental conditions.
- 10. Alleles present at each gene within an organism’s genome
- 11. A local population of interbreeding individuals
- 12. A heritable change in a gene or a chromosome
- 14. All of the DNA in a cell
- 15. The form of selection where the mean phenotype has higher fitness than the phenotypes at either end of the distribution
- 17. The appearance of an organism for a particular characteristic
- 19. A measurable change in a phenotypic character or characters over a geographic region
