答:有相当部分的生物减数分裂在产生配子时进行,但不是一切生物的减数分裂都是在产生配子时进行的。不同种类的生物进行的减数分裂类型是不同的。减数分裂有三种类型。①配子减数分裂:生物在产生配子时进行的减数分裂叫做配子减数分裂。绝大部分动物和人类及部分低等植物如马尾藻、鹿角菜、各种硅藻等属于配子减数分裂生物。②合子减数分裂:部分低等植 A: A considerable part of the biological meiosis occurs when gametes are produced, but not all meiosis of all living things occurs when gametes are produced. Mesenteric types are different for different species of organisms. There are three types of meiosis. ① gametes meiosis: organisms in gametes produced when meiosis is called gametes meiosis. Most animals and humans and some lower plants such as Sargassum, Carotenoids, all kinds of diatoms and other gametophytic meiosis organisms. ② zygotic meiosis: some lower plants
