Genetics

4. The observable physical or physiological traits of an organism (e.g., "Purple flowers").
5. Having two different alleles for a particular gene (e.g., "Pp").
6. The transmission of traits from one generation to the next.
10. A pattern where two dominant alleles are expressed distinctly and simultaneously in the phenotype (e.g., AB blood type).
11. A specific sequence of DNA that encodes for a protein and determines a trait.
12. Each variant for a character, such as purple or white flowers.
13. A variant form of a gene that affects how a trait appears (e.g., the allele for purple vs. the allele for white).

1. Having two identical alleles for a particular gene (e.g., "PP" or "pp").
2. Organisms that, when self-fertilized, produce offspring identical to themselves for several generations; these are homozygous.
3. When a single phenotypic character is determined by the additive effects of two or more genes (e.g., skin color or height).
7. A heritable feature that varies among individuals, such as flower color.
8. The particular physical location or "address" of a gene on a chromosome.
9. The actual genetic makeup or combination of alleles for a trait (e.g., "Pp").
