What is the correct sequence of the steps given here ? Also work out the process depicted in the steps.
(i) Homologous chromosomes move toward opposite poles of the cell; chromatids do not separate
(ii) Chromosomes gather together at the two poles of the cell and the nucleare membranes reform 
(iii) Homologous chromosomes pair and exchange segments 
(iv) Homologous chromosomes align on a central plate
(v) The haploid cells separate completely
(1) The correct sequence is IIIIVIIIV and the process is meiosis-I

(2) The correct sequence is IIIVIVIII and the process is mitosis

(3) The correct sequence is IVIIIIIIV and the process is meiosis-I

(4) the correct sequence is IIVIVIII and the process is mitosis

The total DNA content of each daughter cell is reduced during meiosis because:

1. Chromosomes do not replicate during the interphase preceding meiosis I
2. Chromosomes do not replicate between meiosis I and II
3. Half of the chromosomes from each gamete are lost during fertilization
4. Chromosome arms are lost during crossing over
