Chapter 9, Problem 4MCQ
Summary Introduction
Introduction:
Meiosis is a process of division of a single cell into four daughter cells. This type of division is mainly seen in the germ cells of humans. The daughter cells contain a half the number of chromosomes of their parental cell.

meiosis
Which process leads to independent assortment?
a)The process of separating chromosomes
b)The random alignment of homologs with respect to the others on the metaphase plate
c)The process of forming the mitotic spindle
d)The process of cytokinesis
What is the purpose of mitosis?
a
It ensures that new nuclei have an exact copy of DNA.
b
It ensures the reproduction of mitochondria and chloroplasts.
c
It guarantees that each daughter cell has half the amount of DNA of parent cells.
d
It prevents the occurrence of cancer cells.
