单性生殖和单性结实是生物学上极为普通的概念,两者之间的联系和区别是很明显的。然而,由于人们的一时疏忽,有时竟将这两个概念混淆起来。因此,对这两个概念加以辨别仍然是十分必要的。单性生殖就是进行有性生殖的生物,生殖细胞不经过两两结合就单独发育成新个体的现象。例如,蜜蜂的卵细胞不经过受精可以发育成雄蜂;夏季的蚜虫的卵细胞不经受精就可以发育成雌蚜虫,象这种卵细胞不经过受精而单独发育成新个体的现象称为孤雌生殖。蜜蜂的孤雌生殖又称为产雄孤雌生殖;蚜虫的孤雌生
Parthenogenesis and unisexual fruiting is a very common concept of biology, the relationship between the two and the difference is obvious. However, sometimes these two concepts are sometimes confused by people’s negligence. Therefore, it is still very necessary to distinguish between these two concepts. Parthenogenesis is the phenomenon of sexual reproduction of organisms, germ cells independently developed into a new individual without any combination of two. For example, a bee’s egg cell can develop into a drone without fertilization; aphids’ summer egg cells develop into female aphids without being fertilized, and the phenomenon that such egg cells individually develop into new individuals without fertilization is called parthenogenesis. Parthenogenesis of bees is also called parthenogenesis; parthenogenetic aphids
