| Antibodies | Specialized proteins that aid in destroying infectious agents |
| Centromere | Constricted region of a chromosome and the point at which duplicate DNA strands attach themselves |
| Chromosome | A strand of DNA coiled around and supported by proteins, found in the nucleus of the cell |
| Diploid chromosome number (2n | The total number of chromosomes in a diploid cell |
| Environmental factors | Those "non-biological" factors that are involved in a person's surroundings such as the nature of the person's parents, the person's friends, and the person's behavioral choices |
| Gametes | Haploid cells (n) produced by diploid cells (2n) for the purpose of reproduction |
| Gene | A section of DNA that codes for the production of a protein or a portion of protein, thereby causing a trait |
| Genetic factors | The general guideline of traits determined by a person's DNA |
| Genetics | The science that studies how characteristics get passed from parent to offspring |
| Haploid cells | Cells that have only one of each chromosome |
| Haploid chromosome number (n) | The number of homologous pairs in a diploid cell |
| Interphase | The time interval between cellular reproduction |
| Karyotype | The figure produced when the chromosomes of a species during metaphase are arranged according to size |
| Meiosis | The process by which a diploid (2n) cell forms four gametes (n) |
| Mitosis | The duplication of a cell's chromosomes to allow daughter cells to receive the exact genetic makeup of the parent cell |
| Mother cell | A cell ready to begin reproduction, containing duplicate DNA and centriole |
| Spiritual factors | The quality of a person's relationship with God |
| Vaccine | A weakened or inactive version of a virus that stimulates the body's production of antibodies which can destroy the virus |
| Virus | A non-cellular infectious agent that has two characteristics: (1) It has genetic material inside a protective protein coat (2) It cannot reproduce itself |
