Across
- 3. Allele and genotypic frequencies remain constant assuming that there are no other active evolutionary forces
- 7. Random Heritable changes in DNA/RNA, providing genetic variation that lead to evolution
- 10. Migration of individuals between two populations leading to exchange of genetic materials
- 13. The proportion of a specific allele within a population
- 14. Species with average traits are favored which reduces genetic variation
- 15. Random fluctuations in the frequencies of different gene variants within a population, leading to different changes in the gene pool over time.
Down
- 1. Extreme phenotypes are favored over intermediate phenotypes
- 2. Individuals breed species with selective traits that are used for other purposes
- 4. One extreme phenotype is favored over the other extreme or intermediate traits
- 5. Population size significantly reduced due to natural disasters or other catastrophic event
- 6. Certain traits lead to higher chances of mating, leading to greater reproductive success
- 8. Organisms gain adaptations to their environment and have better chances of survival and reproduction
- 9. Small group of individuals migrate to a new geographic location and establishes a new population
- 11. The number of offspring an individual has that corresponds to their reproductive age
- 12. Heritable traits species gain from evolution that allows them to survive and reproduce in its environment
