Question

during meiosis chromosomes replicated so number of chromosomes increases then it starts dividing which leads to the same number of chromosomes in parents then why it's called as reduction division

​

Answer 1

Answer:

The meiosis divides into two parts

1. Meiosis l
2. Meiosis ll

Explanation:

meiosis l is a reductional division while meiosis ll is equational divsion

1. in meiosis l there are pairing of Homologous chromosome occurs, in a stage of Anaphase l there is no division of centromere, only the pairof Homologous chromosome are unpaired and attached to the spindle fibre of opposite poles. thus each pole have half number of chromosome. and the chromosome were condensed and cell divides into two cells , the each cells are haploid because of the chromosome number in a daughter cell is half of the Parental cell . so it is called Reductional division.
2. Meiosis ll seems like to be mitosis, the two daughter cells (haploid)divides mitotically and form four daughter cell, whose are always haploid . Thus it is called Equational division.
