减数分裂是高中生物学中的重点和难点,在高考中几乎每年都会涉及到。一方面,它是特殊的有丝分裂,是有丝分裂的延伸;另一方面,减数分裂是生物生殖的基础,因此和生物的遗传、变异以及生物的进化等密切联系,涉及面广且深。高考不仅仅是直接考减数分裂的图像和过程,也常出现综合性的题型。 Meiosis is a high school biology key and difficult point in the college entrance examination will be involved almost every year. On the one hand, it is a special mitosis, which is an extension of mitosis. On the other hand, meiosis is the basis of biological reproduction.
