- 4. a viral reproductive stage where the virus's DNA is replicated using the host cell's DNA
- 7. any movement of individuals, and/or the genetic material they carry, from one population to another
- 9. how a new kind of plant or animal species is created
- 10. a mode of reproduction in which a new offspring is produced by a single parent
- 11. the reduction in genomic variability that occurs when a small group of individuals becomes separated from a larger population
- 14. the process by which individuals compete for access to mates and fertilization opportunities
