Across
- 8. organisms that are more adapted to their environment are more likely to survive and pass on the genes that aided their success
- 10. random changes that can potentially lead to new adaptations that increase the fitness of an individual
- 11. individuals with one extreme version of a trait have higher fitnessStabilizing
Down
- 1. a change in the allele frequency of a population as a result of chance events rather than natural selection
- 2. a type of genetic that has been around for years
- 3. the amount of reproduction of an individual compared with the reproductive output
- 4. the permanent movement of genes into or out of a population resulting in a change in allele frequenciesStabilizing individuals with an intermediate version of a trait are the most fit
- 5. individuals with extreme versions of a trait have higher fitness than those with intermediate versionsMutations
- 6. the relative frequency of an allele at a particular locus in a population
- 7. a feather peacock is attracted to a male with the most beautiful tail feathers
- 9. is evolution a random process?
