| 설명 | 두 개의 잘 발육된 개체가 여러 정도의 표면적 결합에 의해서 붙어있는 기형이다. 대부분은 얼굴과 얼굴을 마주보는 유합으로 가슴과 배가 유착된 형태이다. 보통 신체의 앞면, 옆면 또는 시상면에서 결합하고 있다. 또 신체의 극히 일부분만 붙어 있는 것부터 거의 완전히 붙어 있는 것까지 정도가 다양하다. 작고 불완전하게 발육된 개체인 기생체가 보다 크거나 보다 완전하게 발육된 개체인 자생체에 부착되어 있는 경우도 있다. |

| conjoined unequal twins | Conjoined twin's in which one member is nearly normal (host or autosite) and the other (parasite) is small, incomplete, and dependent for its nutrition upon the more nearly normal member. Synonym: conjoined asymmetrical twins. (05 Mar 2000) |
| unequal | 1. Not equal; not matched; not of the same size, length, breadth, quantity, strength, talents, acquirements, age, station, or the like; as, the fingers are of unequal length; peers and commoners are unequal in rank. 2. Ill balanced or matched; disproportioned; hence, not equitable; partial; unjust; unfair. "Against unequal arms to fight in pain." (Milton) "Jerome, a very unequal relator of the opinion of his adversaries." (John Worthington) "To punish me for what you make me do Seems much unequal." (Shak) 3. Not uniform; not equable; irregular; uneven; as, unequal pulsations; an unequal poem. 4. Not adequate or sufficient; inferior; as, the man was unequal to the emergency; the timber was unequal to the sudden strain. 5. <botany> Not having the two sides or the parts symmetrical. Origin: Cf. Inequal. Source: Websters Dictionary (01 Mar 1998) |
| unequal cleavage | Cleavage producing blastomeres of different sizes at the two poles. (05 Mar 2000) |
| unequal crossing over | <cell biology> Crossing over between homologous chromosomes that are not precisely paired, resulting in nonreciprocal exchange of material and chromosomes of unequal length. Favoured in regions containing tandemly repeated sequences. (18 Nov 1997) |

| dizygotic twin | <embryology> Twins which are the result of two separate zygotes, or two separate eggs fertilized by two separate sperm. They can be any combination of sexes (two males, two females, one of each). Compare: monozygotic twins. (09 Oct 1997) |
| twin | 1. Being one of two born at a birth; as, a twin brother or sister. 2. Being one of a pair much resembling one another; standing the relation of a twin to something else; often followed by to or with. 3. <botany> Double; consisting of two similar and corresponding parts. 4. <chemistry> Composed of parts united according to some definite law of twinning. See Twin. Twin boat, or Twin ship, a vessel whose deck and upper works rest on two parallel hulls. Twin crystal. See Twin. <botany> Twin flower, a delicate evergreen plant (Linnaea borealis) of northern climates, which has pretty, fragrant, pendulous flowers borne in pairs on a slender stalk. Twin-screw steamer, a steam vessel propelled by two screws, one on either side of the plane of the keel. Origin: OE. Twin double, AS. Getwinne two and two, pl, twins; akin to D. Tweeling a twin, G. Zwilling, OHG. Zwiniling, Icel. Tvennr, tvinnr, two and two, twin, and to AS. Twi- two. See Twice, Two. 1. One of two produced at a birth, especially by an animal that ordinarily brings forth but one at a birth; used chiefly in the plural, and applied to the young of beasts as well as to human young. 2. <astronomy> A sign and constellation of the zodiac; Gemini. See Gemini. 3. A person or thing that closely resembles another. 4. <chemistry> A compound crystal composed of two or more crystals, or parts of crystals, in reversed position with reference to each other. The relative position of the parts of a twin may be explained by supposing one part to be revolved 180 deg about a certain axis (called the twinning axis), this axis being normal to a plane (called the twinning plane) which is usually one of the fundamental planes of the crystal. This revolution brings the two parts into parallel position, or vice versa. A contact twin is one in which the parts are united by a plane surface, called the composition face, which is usually the same as the twinning plane. A penetration twin is one in which the parts interpenetrate each other, often very irregularly. Twins are also called, according to form, cruciform, geniculated, etc. Source: Websters Dictionary (01 Mar 1998) |

| twin method | A general means of genetic analysis that capitalises on the fact that while twins have the same age and the same intrauterine environment, identical (monozygotic) twins have the same genotype but dizygotic twins are no more alike than sibs and may be of different sex. (05 Mar 2000) |
| twin placenta | The placenta(s) of a twin pregnancy; if dizygotic, the placenta's may be separate or fused, the latter retaining two amniotic and two chorionic sacs (dichorionic diamniotic placenta); if monozygotic, the placenta may be a (05 Mar 2000) |
