module 14 and 15
Across
- 5. a reduction in the gentic diversity of a population caused reduction in size
- 6. change in genetic composition over time
- 7. number of species in a given area
- 9. the process for humans determines which individuals breed
- 10. change in genetic composition of a population as as result of descending from a small number of colonizing individuals
- 12. a random change in genetic code produced by mistaken copying process
- 15. evolution that gives rise to new species etc.
- 16. a trait that improves fitness
- 19. a set of traits expressed in an individual
- 20. the death of the last member in a species
Down
- 1. evolution below the species level
- 2. proportion of individuals w/in different species in given area
- 3. a change in the gentic composition in a population as a result of random mating
- 4. the individuals ability to survive and reproduce
- 8. genetic process when one chromosome breaks off and attaches to another chromosome
- 11. the process where the environment determines which individuals survive and reproduce
- 13. the complete set of genes in an individual
- 14. the process where individuals move from one population to another
- 17. phylogeny branching pattern of evolutionary relationships
- 18. physical location on the chromosomes w/in each organism cell
