Question

Number of chromatids at metaphase is

(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

Answer 1

Correct option  (b) Two  in mitosis and  one in meiosis

Explanation :

 In metaphase, chromosomes ale thick. shortest least coiled and minimum in size. Each chromosome has its both chromatids attached at centromere, oriented at the equator of spindle apparatus.

In meiotic metaphase, each chromosome with two chromatids in a bivalent is connected to the spindle pole of lts side by a kinetochore microtubule instead of two as in metaphase of mitosis.
