- The fundamental physical and functional unit of heredity, which carries information from one generation to the next; a segment of DNA composed of a transcribed region and a regulatory sequence that makes transcription possible.
- The production of equal numbers (50 percent) of each allele in the meiotic products (e.g., gametes) of a heterozygous meiocyte.
