Verified by Experts

The correct Answer is:
(a)Meiosis consists of two divisiob:meiosis-I and meiosis-II.These occur in rapid succession.the chromosomes replicate only once.
(b)Mieotic division:Four daughter cells mieotic division:four daughter cells
(c)Meiosis results in the formation of 4 daughter cells,each having half the number of chromosomes and half of the nuclear DNA amount present in the parent cell.
