加拿大广播公司:研究发现,跟陌生人相比我们与朋友之间的基因更为相似,这一发现为"物以类聚,人以群分"的说法提供了新的佐证.遗传学家发现,无血缘关系的朋友之间有百分之一的基因是相似的.
Canada's CBC carries a report saying: You may have more in common with your friends than you think. Research reveals that mates have a remarkable number of the same genes.
The study, which gives new weight to the saying 'birds of a feather flock together', found that pals share significantly more DNA than strangers.
Geneticists discovered that unrelated friends have a 1 per cent of genes that match – about the same as fourth cousins, who share great-great-great grandparents.
