Question

Number of chromatids per chromosome at metaphase is
A. two each in mitosis and meiosis
B. two in mitosis and one in meiosis
C. two in mitosis and four meiosis
D. one in mitosis and two in meiosis

Answer 1

Correct Answer - A
In metaphase, chromosomes are 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 its side by a kinetochore microtubule instead of two as in metaphase of mitosis.
