|---|---|---|---|
| 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. |

| chromosome segregation | <cell biology> The orderly separation of one copy of each chromosome into each daughter cell at mitosis. (18 Nov 1997) |
|---|
| mitotic segregation | <genetics> Mitotic recombination. (18 Nov 1997) |
|---|---|
| segregation | 1. The act of segregating, or the state of being segregated; separation from others; a parting. 2. <geology> Separation from a mass, and gathering about centers or into cavities at hand through cohesive attraction or the crystallizing process. Origin: L. Segregatio: cf. F. Segregation. Source: Websters Dictionary (01 Mar 1998) |
| segregation analysis | In genetics, the enumeration of progeny according to distinct and mutually exclusive phenotypes; used as a test of a putative pattern of inheritance, e.g., mendelian, dominant autosomal, epistatic, age-dependent. (05 Mar 2000) |
| segregation of chromosomes | <cell biology, genetics> The separation of pairs of homologous chromosomes that occurs at meiosis so that only one chromosome from each pair is present in any single gamete. (18 Nov 1997) |
| segregation ratio | In genetics, the proportion of progeny of a particular genotype or phenotype from actual matings of specified genotypes. The test of a Mendelian hypothesis is the comparison of the segregation rate with the Mendelian rate. (05 Mar 2000) |
| law of segregation | Factors that affect development retain their individuality from generation to generation, do not become contaminated when mixed in a hybrid, and become sorted out from one another when the next generation of gametes is formed. Synonym: Mendel's first law. (05 Mar 2000) |
| accessory chromosome | A chromosome existing without its normal homologous chromosome; at the reduction division of gametogenesis an accessory chromosome is likely to be included in one daughter cell and not in the other, but may be lost completely by lagging behind on the equatorial plate. Synonym: monosome, odd chromosome, unpaired allosome, unpaired chromosome. (05 Mar 2000) |
| acentric chromosome | A fragment of a chromosome lacking a centromere and unable to attach to the mitotic spindle, therefore unable to take part in the division of a nucleus and randomly distributed in daughter cells. Synonym: acentric fragment. (05 Mar 2000) |
| acrocentric chromosome | A chromosome with the centromere placed very close to one end so that the short arm is very small, often with a satellite. (05 Mar 2000) |
| balanced chromosome | <genetics> A chromosome which is unable to pair with its homologue and participate in homologus recombination during meiosis because it contains several inversion mutations (that is, has segments which have become flip-flopped). (09 Oct 1997) |
| B chromosome | <genetics> Small acentric chromosome, part of the normal genome of some races and species of plants. (18 Nov 1997) |
| bivalent chromosome | A pair of chromosome's temporarily united. (05 Mar 2000) |
| male chromosome complement | The large majority of males have a 46, xy chromosome complement (46 chromosomes including an x and a y chromosome). A minority of males have other chromosome constitutions such as 47,xxy (47 chromosomes including two x chromosomes and a y chromosome) and 47,xyy (47 chromosomes including an x and two y chromosomes). (12 Dec 1998) |
| marker chromosome | An abnormal chromosome that is distinctive in appearance but not fully identified. For example, the fragile x chromosome was once called the marker x. (12 Dec 1998) |
| p arm of a chromosome | The short arm of a chromosome (from the french petit meaning small). All human chromosomes have 2 arms: the p and q arms. (12 Dec 1998) |
