例句: Genome analysis to identify paralogous sequences shows that many genes belong to families; the 20,000 to 25,000 genes identified in the human genome fall into ~15,000 families, so the average gene has ~2 relatives in the genome. |
用于鉴定种内同源序列的基因组分析显示,很多基因属于基因家族;人类基因组计划所确定的20000~25000个基因可归类到15000个家族,所以在基因组中平均每个基因均有约2个与它亲缘关系相近的基因。 |

例句: Gene families vary enormously in the degree of relatedness between members, from those consisting of multiple identical members to those for which the relationship is quite distant. |
在不同的基因家族中,其成员相关程度差异很大,有些家族由若干完全一致的成员组成,而有些家族成员之间关系很远。 |

例句: Some pseudogenes have the same general structure as functional genes, with sequences corresponding to exons and introns in the usual locations. |
一些假基因与功能基因具有一样的通用组织结构,在常见位置存在对应的外显子和内含子。 |

intact gene |
每个基因 |

例句: When an intact gene is involved, duplication generates two copies of a gene whose activities are indistinguishable, but then usually the copies diverge as each accumulates different substitutions. |
当一个完整基因产生它的一份重复拷贝时,两者在基因活性上是难以区别的,但当每个基因积聚了不同突变时,这种拷贝之间的趋异性(divergence)也往往就产生了。 |
