- Genotype: The genetic makeup of an individual, represented by the alleles they possess.
3. Physiology Terms
- Hormone: Chemical messengers that regulate physiological processes in the body.
- Synapse: The junction between two neurons where communication occurs.
4. Immunology Terms
- Antigen: A substance that can provoke an immune response.
- Pathogen: An organism that causes disease, such as bacteria or viruses.
5. Development Terms
- Fertilization: The fusion of sperm and egg to form a zygote.
- Gestation: The period of development of the embryo/fetus inside the womb.
