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