本综述系统阐述了西瓜（Citrullus lanatus L.， 2n=22）单倍体诱导技术中，离体（in vitro）花药培养（雄核发育，androgenesis）与子房培养（雌核发育，gynogenesis）的研究现状。文章指出，基因型、植物生长调节剂（PGRs）及培养条件是关键影响因素。该技术能高效创制纯 ...

Ant queens do not usually blur species lines, yet the Iberian harvester ant (Messor genus) does exactly that. A new study reports queens that produce their own species and also generate males of a ...

Mice with two fathers and no mother have now had offspring of their own. The study is a breakthrough in androgenesis – that is, asexual reproduction using only genetic material from male animals.

The first mice to be created from two fathers, a phenomenon known as androgenesis, have now produced healthy offspring for the first time. Researchers implanted two sperm in an egg with its nucleus ...

Add Yahoo as a preferred source to see more of our stories on Google. The first mice to be created from two fathers, a phenomenon known as androgenesis, have now produced healthy offspring for the ...

In a major scientific achievement, scientists in China have managed to bring baby mice into the world using two fathers, and those mice later grew up and had babies of their own. The breakthrough, led ...

For the first time, mice born to two fathers have grown up and produced offspring, scientists in China have revealed. The researchers at Shanghai Jiao Tong University managed to insert two sperm cells ...

为解决男性不育症中精子稀缺及遗传病胚胎筛选的伦理问题，Weill Cornell Medicine团队通过雄核发育（androgenesis）技术成功复制小鼠精子基因组，利用8细胞期单倍体胚胎获得携带相同父源单倍型的健康子代。该研究证实了精子复制技术在保留特定基因型、减少胚胎 ...
