Additive genetic effects

|
Additive genetic effectsA mechanism of quantitative inheritance such that the combined effects of genetic alleles at two or more gene loci are equal to the sum of their individual effects.
RELATED TERMS--------------------------------------
Mechanism
The arrangement or association of the elements or parts of anything in relation to the effect they generate; the combination of mental processes by which an effect is generated.
Genetic
Hereditary. Having to do with the genes.
Gene
1. A unit of DNA that carries information for the biosynthesis of a specific product in the cell. 2. Ultimate unit by which inheritable characteristics are transmitted to succeeding generations in all living organisms. Genes are contained by, and arranged along the length of, the chromosome. The gene is composed of deoxyribonucleic acid (DNA). Each chromosome of each species has a definite number and arrangement of genes, which govern both the structure and metabolic functions of the cells and thus of the entire organism.
SIMILAR TERMS--------------------------------------
Addiction
Strong dependence or habitual use of a substance or practice, despite the negative consequences of its use.
Addiction treatment
A set of medical actions aiming to reduce and reverse addiction.
Addiction, computer
See: Computer addiction.
Addictiveness
A substance's power to make users dependent (addicted) to its further use. Substances are less or more addictive depending on their chemical composition and their effects on the body and mind.
Addison's disease
Addison's disease (also known as chronic adrenal insufficiency, or hypocortisolism) is a rare endocrine disorder. It is a disease that results from a decrease in corticosteroid secretion from the adrenal gland.
Addisonian anemia
A blood disorder caused by a lack of vitamin B12. Patients who have this disorder do not produce the substance in the stomach that allows the body to absorb vitamin B12. This substance is called intrinsic factor (IF). Addisonian anemia, also called pernicious anemia (PA), is characterized by the presence in the blood of large, immature, nucleated cells (megaloblasts) that are forerunners of red blood cells. (Red blood cells, when mature, have no nucleus). It is thus a type of megaloblastic anemia.
PREVIOUS AND NEXT TERMS--------------------------------------
Adapter protein
A protein acts as a connecting molecule. An adapter protein is critical to intermolecular interactions and plays a role in the regulation of signal transduction initiated by engagement of surface receptors on all cell types. Some adapter proteins are expressed in all tissues, while the expression of other adapter proteins is restricted to specific tissues.
ADCC (antibody-dependent cell-mediated cytotox.)
An immune response in which antibodies, by coating target cells, makes them vulnerable to attack by immune cells. Antibody-dependent cell-mediated cytotoxicity is commonly (and blissfully) abbreviated ADCC.
ADD (attention deficit disorder)
"An inability to control behavior due to difficulty in processing neural stimuli. In November, 1998 the National Institutes of Health (NIH) issued a consensus report developed by a panel of experts. The panel concluded that:

Adducted thumbs with mental retardation
"A syndrome with the following characteristic features:
Adduction
"Movement of a limb toward the midline of the body. The opposite of adduction is abduction. An adductor muscle pulls toward the midline of the body. For example, the adductor muscles of the legs pull the legs toward the midline of the body so the legs are closer together. From the Latin prefix ""ad"" meaning ""toward"" + ""ducere"" meaning ""to draw or lead"" = ""to draw toward."""
Adductor muscle
"Any muscle that pulls a body part toward the midline. For example, the adductor muscles of the legs pull the legs toward the midline of the body so the legs are closer together. The word ""adductor"" comes from the Latin prefix ""ad"" meaning ""toward"" + ""ducere"" meaning ""to draw or lead"" = ""to draw toward."" The opposite of ""adductor"" is ""abductor."" An adductor muscle opposes an abductor muscle."
Adductor spasmodic dysphonia
A disorder in which sudden muscle spasms cause the vocal folds (or vocal cords) to slam together. See: spasmodic dysphonia.
ADE
Adverse drug event. See: Adverse reaction.
