| identical twins | Identical twins, twins which are the result of a single zygote (fertilized egg) splitting into two cell masses and becoming two individuals. The twins are genetically identical and are always of the same sex (both males or both females). Compare: dizygotic twins. (09 Oct 1997) |

| enzygotic twins | Synonym: monozygotic twins. (05 Mar 2000) |
| twins, dizygotic | Two offspring produced in the same pregnancy from separate ova fertilised at the same time. (12 Dec 1998) |
| twins, monozygotic | Two offspring developed from one fertilised ovum. (12 Dec 1998) |
| uniovular twins | Identical twins, twins which are the result of a single zygote (fertilized egg) splitting into two cell masses and becoming two individuals. The twins are genetically identical and are always of the same sex (both males or both females). Compare: dizygotic twins. (09 Oct 1997) |
| fraternal twins | Fraternal twins are siblings who have shared a common uterine environment. They are due to fertilization of two different ova by different sperm. Fraternal twins are also called dizygotic twins. (12 Dec 1998) |
| abortion, incomplete | Abortion in which not all the products of conception have been expelled. (12 Dec 1998) |
| incomplete | 1. Not complete; not filled up; not finished; not having all its parts, or not having them all adjusted; imperfect; defective. "A most imperfect and incomplete divine." (Milton) 2. <botany> Wanting any of the usual floral organs; said of a flower. <mathematics> Incomplete equation, an equation some of whose terms are wanting; or one in which the coefficient of some one or more of the powers of the unknown quantity is equal to 0. Origin: L. Incompletus: cf. F. Incomplet. See In- not, and Complete. Source: Websters Dictionary (01 Mar 1998) |
| incomplete abortion | <obstetrics> A clinical situation where the foetus has died but has not been completely expelled from the uterus. (13 Nov 1997) |
| incomplete achromatopsia | Impaired, but not absent, colour vision with less severely reduced visual acuity than in complete achromatopsia; inherited as an autosomal recessive or as an X-linked disorder (blue cone monochromism; pi cone monochromatism ). (05 Mar 2000) |
| incomplete agglutinin | Antibody that binds to antigen but does not induce agglutination. These antibodies are usually of the IgG class and are referred to as incomplete antibody. (05 Mar 2000) |
| incomplete alexia | <clinical sign> A term used to describe a condition in which an individual with normal vision is unable to properly interpret written language. Dyslexia is more common in males and is often first recognised as a reading difficulty in the first grade. Individuals can see and recognise letters but are unable to spell and write words. They have no impairment of object or picture identification. Dyslexia is not related to intelligence and in fact several famous scholars were thought to be dyslexic (for example Albert Einstein, Thomas Edison). The exact cause of dyslexia is unknown.

| incomplete antibody | An "incomplete" form of antibody that may coat antigen, but which according to the "lattice theory" does not have a second receptor for attachment to another molecule of antigen; in the case of Rh+ erythrocytes, such an anti-Rh antibody may coat the cells but not cause them to agglutinate in saline; however, agglutination does occur when such coated cells are suspended in serum or other protein media, such as albumin, therefore called serum agglutinin. Synonym: incomplete antibody, inhibiting antibody. (05 Mar 2000) |
| incomplete antigen | <immunology, molecular biology> Could be considered an isolated epitope: although a hapten (by definition) has an antibody directed against it, the hapten alone will not induce an immune response if injected into an animal, it must be conjugated to a carrier (usually a protein). The hapten constitutes a single antigenic determinant, perhaps the best known example is dinitro phenol (DNP) that can be conjugated to BSA and against which antiDNP antibodies are produced (antibodies to the BSA can be adsorbed out). Because the hapten is monovalent, immune complex formation will be blocked if the soluble hapten is present as well as the hapten carrier conjugate (assuming there is more than one hapten per carrier then an immune precipitate can be formed). Competitive inhibition by the soluble small molecule is sometimes referred to as haptenic inhibition and this term has carried over into lectin mediated haemagglutination where monosaccharides are added to try to block haemagglutination: the blocking sugar defines the specificity of the lectin.

| incomplete ascertainment | Method of locating affected individuals in which probability of locating any specific patient has a known value between 0 and 1. Synonym: truncate ascertainment. (05 Mar 2000) |
