- 9. ____ is a physical characteristic where multiple genes determine the phenotype of a trait (ex. Human height).
- 10. _________ is the type of dominance where both versions of the trait are equally powerful and there is a blending of traits if the genotype is heterozygous (ex. Pink four o’clock flowers).
- 11. The ______ is the physical appearance of an organism.
- 12. ______ is the type of dominance where both versions of the trait are equally powerful and both traits are shown if the genotype is heterozygous (ex. Speckled chickens).
