7. An allele that often does not result in a trait being observed unless it is the only allele present.
8. The likelihood an event will occur (like a coin flip).
9. When two distinct individuals are mated.
11. The study of the inheritance of traits from parent(s) to offspring.
12. Appearance/behavior of an organism.
14. Scientist and priest whose study of pea plants created the science of "Genetics"
16. Mendel's 2nd Law; there are two copies of a gene, but only one gets passed on via gametes--now explained by meiosis.
17. A segment of DNA responsible for a trait; originally called "Unit factors".
18. Mendel's 3rd Law; multiple genes do not have to be inherited together.
19. Tool used to predict the genetic outcome of breeding.

1. A general characteristic of an organism (e.g. Eye color, hair color).
2. A combination of traits not found in either of an organism's parents.
3. A cross in which an experimenter is observing only one character.
4. An allele that, if present, will result in a trait being observed.
5. A specific property of an organism's characteristic (e.g. brown eyes, red hair).
6. Having two varieties of allele (Tt).
10. Genetic make-up of an organism.
13. Having only one variety of allele (TT, tt).
15. Mendel's 1st Law; that genes can have different varieties and only some varieties of traits appear.
