同源染色体 Homologous chromosome

(重定向自Homologs)

同源染色体是在二倍体生物细胞中,形态、结构基本相同的染色体,并在减数第一次分裂(参考减数分裂)的四分体时期中彼此联会(若是三倍体及其他奇数倍体生物细胞,联会时会发生紊乱),最后分开到不同的生殖细胞(即精子、卵细胞)的一对染色体,在这一对染色体中一个来自母方,另一个来自父方。而在同源染色体中,通常不谈x y染色体,X Y染色体主要为部分同源的染色体,通常在谈及时,会将此另外谈论,因为在严格定义下同源染色体主要是在一对的染色体中 ,有同样的大小,形状,基因座,所以在此XY染色体则为不同大小,形状,所以有些书本中,不予认为是同源染色体。

Homologous chromosome 同源染色体

(重定向自Homologs)
As this karyotype displays, a diploid human cell contains 23 pairs of homologous chromosomes. The cell has two sets of each chromosome; one of the pair is derived from the mother and the other from the father. The maternal and paternal chromosomes in a homologous pair have the same genes at the same loci, but possibly different alleles.
 During the process of meiosis, homologous chromosomes can recombine and produce new combinations of genes in the daughter cells.
 Sorting of homologous chromosomes during meiosis.
1. Meiosis I 2. Meiosis II 3. Fertilization 4. Zygote
Nondisjunction is when chromosomes fail to separate normally resulting in a gain or loss of chromosomes. In the left image the ultra violet arrow indicates nondisjunction taking place during meiosis II. In the right image the green arrow is indicating nondisjunction taking place during meiosis I.

A couple of homologous chromosomes, or homologs, are a set of one maternal and one paternal chromosomes that pair up with each other inside a cell during meiosis. These copies have the same genes in the same loci where they provide points along each chromosome which enable a pair of chromosomes to align correctly with each other before separating during meiosis. This is the basis for Mendelian inheritance which characterizes inheritance patterns of genetic material from an organism to its offspring parent developmental cell at the given time and area.
