近親繁殖的意思、翻譯和例句

是什麼意思

「近親繁殖」是指在同一家庭或有血緣關係的個體之間進行繁殖的行為。這種繁殖方式可能導致基因多樣性降低,增加後代患遺傳疾病的風險。在動植物育種中,近親繁殖有時會被用來固定某些優良性狀,但長期進行可能會對種群的健康和適應性造成負面影響。

用法:

指在同一種族或品系內進行繁殖,通常是指親屬之間的交配。這種繁殖方式可能會導致基因缺陷的增加,因為近親之間的基因相似度高,可能會使隱性遺傳疾病表現出來。在農業和動物育種中,近親繁殖有時會被用來固定某些優良性狀,但長期進行會對種群的健康造成威脅。

例句及翻譯:

例句 1:

近親繁殖可能會導致後代的遺傳疾病增加。

Inbreeding can lead to an increase in genetic disorders in offspring.

例句 2:

農場主決定避免近親繁殖,以保持牲畜的健康。

2:Line breeding

用法:

一種特定形式的近親繁殖,通常是指在同一血統中選擇性地繁殖,以保持或強化某些期望的性狀。這種方法常用於犬種和馬匹的繁殖中,目的是保留某些優良特徵,但也可能增加遺傳問題的風險。
