|---|---|---|---|
| 설명 | 암수의 성을 결정하는 데 중요한 구실을 하는 염색체. 이것에 대하여 보통의 염색체를 보통염색체라고 한다. 암수의 구별이 있는 생물에서는 암수에 따라 다른 형과 수를 나타내는 염색체이며, 보통염색체에 비해 염색성이나 행동에서 차이가 있다. 특히 동물의 성염색체는 그런 경향이 강하다. 휴지기 및 핵분열 전기에 뚜렷한 이상응축을 나타내며 감수분열 때는 다른 염색체보다 먼저 앞서거나 끌려가는 행동을 보여준다. |

|---|---|---|---|
| 설명 | 유전정보를 담고 있는 DNA가 모여서 이루는 구조물로 핵속에 위치한다. 세포가 분열할 때 이것을 더욱 뚜렷이 관찰할 수가 있다. 이것은 사람처럼 고등생물체에서 너무나 많은 정보를 담고 있어, 엄청난 길이(사람에 있어서 전 DNA를 길이로 따지면 약 2m가 된다)가 된 DNA를 작은 핵이란 공간속에 보관하기 위해서 만들어진 구조이다. 이 염색체의 수는 생물의 종에 따라 다르며 사람의 경우는 46개이다. |

|---|---|---|---|
| 설명 | 염색체의 수나 구조의 이상. 이상이 생긴 세포나 개체는 유전적인 이상을 일으켜 사람의 경우, 다운 증후군-터너 증후군 따위의 여러 가지 형태로 나타난다. |

| morphological | <biology> Of, pertaining to, or according to, the principles of morphology. Morpholog"ically. Origin: Cf. F. Morphologique. Source: Websters Dictionary (01 Mar 1998) |
| morphological adaptation | <ecology> A structural feature that aids in fitting a species to its particular environment (for example, buttressed bases, adventitious roots and aerenchymous tissue). (09 Oct 1997) |
| morphological features | Properties related to the external structure of soil (such as colour and texture) or of plants. (09 Oct 1997) |
| aberration | 1. <ophthalmology> Any error that results in image degradation. Such errors may be chromatic, spherical, astigmatic chromatic, distortion, or curvature of field: and can result from design or execution, or both. 2. <physics> Failure of an optical or electron-optical lens to produce exact geometrical (and chromatic) correspondence between an object and its image. In a video camera tube or cathode-ray tube, aberrations are when the (electrostatic or electromagnetic) lens does not bring the electron beam to sharply focused points uniformly on the target or screen, or to correct geometrical positions, as the beam is deflected. 3. <zoology> A term which, if used to denote a number of individuals within a species, unequivocally signifies infrasubspecific rank. See: aberration, chromatic, aberration, spherical. (09 Jan 1998) |
| aberration, chromatic | <optics> A defect in a lens or optical system due to the greater refraction of shorter wavelengths over that of loner ones at a lens surface. Hence the focal length of a simple lens is shorter for blue than for red rays. This dispersion of the wave-lengths will cause colour fringes in the image field of a lens with such an aberration. (05 Aug 1998) |
| aberration, spherical | <optics> A lens defect whereby image forming rays of one colour, passing through the outer zones of a lens come to focus at a different distance from the lens than do those of more central rays. With a simple spherical (or plano-spherical) lens the outer rays always meet the axis closer to the lens than do more central rays and the lens is uncorrected or undercorrected. When the reverse is true the lens has been overcorrected. (05 Aug 1998) |
| ventricular aberration | Abnormal intraventricular conduction of a supraventricular beat, especially where surrounding beats are normally conducted. Synonym: ventricular aberration. (05 Mar 2000) |
| mental aberration | Disturbed thought or behaviour that connotes a psychological or psychiatric impairment. See: delusion. (05 Mar 2000) |
| meridional aberration | An aberration produced in the plane of a single meridian of a lens. (05 Mar 2000) |
| chromatic aberration | When using white light through a lens system, it is inevitable that different wave lengths (colours) are brought to a focus at slightly different points. As a consequence, there are chromatic aberations in the image, good microscope objectives are therefore corrected for this at two wave lengths (achromats) or at three wave lengths (apochromats), as well as for spherical aberration. (18 Nov 1997) |
| chromosomal aberration | Any abnormality of a chromosome's number or structure. (09 Oct 1997) |
| monochromatic aberration | A defect in an optical image arising because of the nature of lenses; the main types are spherical, coma, curvature, and distortion aberration, and astigmatism of oblique pencils. (05 Mar 2000) |
| colour aberration | When using white light through a lens system, it is inevitable that different wave lengths (colours) are brought to a focus at slightly different points. As a consequence, there are chromatic aberations in the image, good microscope objectives are therefore corrected for this at two wave lengths (achromats) or at three wave lengths (apochromats), as well as for spherical aberration. (18 Nov 1997) |
| coma aberration | The distortion of image formation created when a bundle of light rays enters an optical system not parallel to the optic axis. <botany> Any tuft, as the hairs on a seed, or the greenery on a radish or a pineapple. Synonym: coma. Origin: G. Kome, hair, foliage (05 Mar 2000) |
