自倍體的意思、翻譯和例句

是什麼意思

「自倍體」是指生物體的染色體數量是其基數的整數倍,通常是兩倍(2n),這種情況在植物和動物中都可以見到。自倍體的形成通常是由於染色體的複製或細胞分裂過程中的錯誤所導致的,這使得細胞內的染色體數量增加。自倍體通常具有較大的細胞和較高的生長速率,並且在植物育種中常被利用來提高作物的產量和抗病性。

1:Autopolyploid

用法:

指的是同一物種內的染色體數量增加,通常是由於基因複製或細胞分裂中的錯誤。這種情況在植物中非常常見,特別是在農作物的育種中,因為自倍體通常能夠表現出較強的生長能力和更好的抗逆性。

例句及翻譯:

例句 1:

自倍體植物通常比二倍體植物更大。

Autopolyploid plants are often larger than diploid plants.

例句 2:

自倍體的形成可以通過化學物質促進。

The formation of autopolyploids can be induced by chemicals.

例句 3:

許多農作物都是自倍體品種,以提高產量。

Many crops are autopolyploid varieties to enhance yield.

2:Polyploid

用法:

泛指擁有多於兩套染色體的生物,這可以是自倍體或異倍體。多倍體在植物界特別常見,因為它們能夠適應不同的環境並表現出更高的生物量。

例句及翻譯:

例句 1:

多倍體植物通常具有更高的生長速率。

Polyploid plants often exhibit higher growth rates.

例句 2:

許多水果和蔬菜都是多倍體,這使它們更具商業價值。

Many fruits and vegetables are polyploid, which makes them more commercially valuable.

例句 3:

多倍體的形成可以通過自然選擇或人為育種來實現。

The formation of polyploids can occur through natural selection or through human breeding.

3:Chromosome duplication

用法:

指染色體在細胞分裂過程中進行的複製,這是自倍體形成的基礎。當染色體複製不完全或在細胞分裂時出現錯誤,就會導致自倍體的形成。

例句及翻譯:

例句 1:

染色體複製的過程對於細胞的正常功能至關重要。

The process of chromosome duplication is crucial for normal cell function.

例句 2:

在細胞分裂中,染色體複製的失誤可能導致自倍體的形成。

Errors in chromosome duplication during cell division can lead to the formation of autopolyploids.

例句 3:

研究顯示,染色體複製的異常可能與癌症有關。

Studies show that abnormalities in chromosome duplication may be linked to cancer.

4:Genetic duplication

用法:

指基因或染色體的重複,這是導致自倍體的主要機制之一。基因重複可以增加遺傳變異,並可能對生物的適應性產生影響。

例句及翻譯:

例句 1:

基因重複是進化過程中的一個重要機制。

Genetic duplication is an important mechanism in the process of evolution.

例句 2:

一些自倍體物種的基因重複使它們能夠適應環境變化。

The genetic duplication in some autopolyploid species allows them to adapt to environmental changes.

例句 3:

研究顯示,基因重複與多種疾病有關。

Research shows that genetic duplication is associated with various diseases.
