Question

Meiosis II is said to be similar to mitosis, however the two differ in some aspects like
a. In meiosis II, the two daughter cells formed from each cell are generally genetically different
b. Meiosis II is initiated immediately after cytokinesis
c. In animals, mitosis takes place in both haploid and diploid cells
d. Synaptonemal complex is formed in meiosis II
e. Centromere does not divide in meiosis II
The correct statements are

Solution

The correct option is A a, d & e
In Meosis II the daughter cells formed are genetically different because recombination of chromosomes takes place which gives them genetic variety.
Cytokinesis is initiated immediately after Meosis II.
Mitosis can take place in both haploid and diploid cells. It involves maintaining the number of chromosomes in the new cells and No reductional division takes place.
Synaptonemal complex is formed in meiosis I in the zygotene phase and helps in recombination of genes.
during anaphase to the centromere splits and the chromosomes are called in different and opposite directions. Hence meiosis II involve division of centromere. 
So the correct answer is ' a, c'.
