- 9. situation where the phenotypes of both alleles are exhibited in the heterozygote because both alleles affect the phenotype in separate ways
- 11. observable inheritable feature that varies among individuals
- 12. rule of probability stating that the probability of any one of two mutually exclusive events occurring can be determined by adding their individual probabilities

- 3. Any detectable variant in a genetic character
- 4. organism that is heterozygous with respect to two genes of interest
- 5. observable physical and physiological traits of an organism determined by genetic makeup
- 6. heritable feature that varies continuously over a range rather than in an either or fashion
- 7. An additive effect of two or more genes on a single phenotypic character
- 8. determines the probability of two or more independent events by multiplying the probability of one event by the probabilities of the other events
