3. A physical characteristic or an organism, determined by genetics (e.g. eye colour).
5. The process through which RNA codes for the formation of proteins.
8. The combination of alleles possessed by an organism.
10. Gametes are _________ cells and possess only half the full complement of chromosomes (e.g. 23 in humans).
15. A mass of uncontrolled cell growth (may also be cancerous).
16. An organism that possesses two different alleles for a trait.
18. A number describing how likely an event is.
