These creatures reproduce by parthenogenesis - also called 'virgin birth', this is the process where the female can reproduce without a mate - the term used for an animal's sexual partner.

这些生物通过孤雌生繁 —— 也叫做“单性生”，这是指雌性可以在没有配偶 —— 这个名词被用来指代动物的性伴侣 ——的情况下繁的过程。

But some aphids, katydids, lizards, geckos, and snakes only ever reproduce via parthenogenesis.

有些蚜虫、蝈蝈、蜥蜴、壁虎、蛇等只进行孤雌生。

The most likely explanation, something called parthenogenesis.

最可能的解释是一种称为孤雌生的东西。

It's a product of parthenogenesis which means it was born from an unfertilized egg.

这种繁叫孤雌生这就是说它由没有受过精的卵来。

Bdelloid rotifers, meanwhile, have been reproducing parthenogenetically for 60 million years.

与此同时，蛭形轮虫已经孤雌生了近 6000 万年。

In fact, some animals only ever undergo parthenogenesis, while others can reproduce both sexually and parthenogenetically.

实际上，有些动物只进行孤雌生，另外一些则既可以进行有性繁，也能进行孤雌生。

In parthenogenesis, an embryo develops from an unfertilized egg cell that doubles its own chromosome count.

在孤雌生中，胚胎由未受精的卵细胞在染色体数目翻倍后发育来。

But scientists have observed an accumulation of harmful mutations in parthenogenetic stick insects that are absent in their sexual relatives.

但科学家们已经发现，一种孤雌生的粘虫在缺乏性伴侣时积累起有害的变异。

Mayflies can sometimes default to parthenogenesis if there are no males available, which is especially handy because they've only got a day or so to reproduce before dying.

蜉蝣在没有雄性存在的条件下可以转为孤雌生，这非常方便，因为它们在死亡前只有一天左右的时间进行繁。

Parthenogenesis, meanwhile, requires only one parent.

孤雌生只需要一位父母。

Through an asexual reproduction process called parthenogenesis.

通过一种称为孤雌生的无性繁过程。

Parthenogenesis is a type of asexual reproduction where an embryo develops without previous fertilization.

孤雌生是一种无性生，其中胚胎无需先前受精即可发育。

Cultivated bananas reproduce asexually, through a process known as parthenogenesis, which literally means " virgin birth." Most plants have male and female flower-parts and seeds, that are pollinated with the help of things like the wind, or bees.

种植的香蕉通过一种称为孤雌生的过程进行无性繁，字面上的意思是“处女生育” 。 大多数植物都有雄性和雌性的花部以及种子，这些种子在风或蜜蜂的帮助下进行授粉。

In the summer, when food is abundant, pea aphids can rely on parthenogenesis, allowing their population to explode under favorable conditions.

在夏季食物充足的时候，豌豆蚜可以孤雌生，让种群数量在有利环境中迅速膨胀。

It's called parthenogenesis or virgin birth and it will make a brand new, a number of baby lizards and they're all females.

这叫做孤雌生或处女生育，它会产生一批全新的小蜥蜴，且它们全都是雌性的。

But this wasn’t a case of cloning or parthenogenesis -- sometimes called " virgin birth" -- neither of which requires sperm.

但这并不是克隆或孤雌生——有时被称为“处女生育”——这两种方式都不需要精子。

In a parthenogenetic population, on the other hand, individuals can only reproduce using their own genetic material.

另一方面，在孤雌生的群体中，个体只能利用自身的遗传物质进行繁。

Parthenogenesis is characterized by a lack of genetic diversity, which can lead to harmful mutations and diseases.

孤雌生的特点是缺乏遗传多样性，这可能导致有害的突变和疾病。

Scientists also confirmed that parthenogenesis was taking place in some wild snake populations.

科学家们也发现，孤雌生还会在某些野生蛇类种群中发生。

Mayflies can default to parthenogenesis, which is quite handy because some females live for less than 5 minutes.

蜉蝣可以默认进行孤雌生，这非常方便， 因为有些雌性寿命不到 5 分钟。
