Mark the correct statement:

1 The stage between two successive meiotic division is generally long lived

2 In plant cells, wall formation starts in the centre of the cell and grows outward to meet the existing lateral walls

3 Meiosis results in conservation of specific chromosomes number of each species across generations in asexually reproducing organisms

4 Telophase - I can last for months or year
