南非的一只海角蜂工蜂因为拥有罕见的基因特质,可以通过克隆自己来实现自行繁衍。在过去的30多年里,这只海角蜂工蜂已经成功地克隆出数百万只“自己”,这个发现刷新了人们的认知。
A kind of South African honeybees can clone themselves and cre⁃ate more bees like them.Genetic analysis reveals that their cloning hab⁃it began on a single honeybee in 1990 that cloned itself successfully and produced queens that could take over the hive,according to New Scientist.The process of asexual reproduction or parthenogenesis(单性生殖)is common in lower plants or animals,like ants,wasps,and bees.However,having an offspring that is identical to the parent is uncommon because genetic material is often mixed up in a process called recombination that could result in an off⁃spring with a slightly different genetic make⁃up。
