Question
Number of chromatids at metaphase is
Options
A.two each in mitosis and meiosis
B.two in mitosis and one in meiosis
C. two in mitosis and four in meiosis
D.one in mitosis and two in meiosis
Solution
I metaphase , chromosomes are thick, shortest least coiled and minimum in size. Each chromo some has its both chromatids attached at centromere, oriented at the equator of spindle appa ratus. In meiotic metaphase, each chromosome with two chromatids in a bivalent is connected to the spindle pole of its side by a kinetochore microtubule instead of two as in metaphase of mitosis.
