Describe what happens during prophase i and metaphase i and how these phases play an important role in the genetic diversity of the daughter cells produced

Prophase 1
                      Prophase 1 consists of following stages.

1. Leptonen
                    The chromosome get condense and attach to nuclear membrane through telomeres.

2. Zygotene
                   In this step synapsis (pairing of homologous chromosomes) occurs.

3. Pachytene
                    Between non sister chromatids crossing over occurs.

4. Diplotene
                     Synapsis ends, while non sister chromatids remain attached at chiasmata.

5. Diakinesis
                      chromosome become fully condense and nuclear membrane disappers.

Metaphase 1
                      During this stage chromosomes arrange themselves in the center at equator and form equatorial plate.

Role in genetic diversity
                                         Crossing over is one of the most important phenomenon responsible for genetic recombination, because the offspring which are formed from parents are genetically variant and are best adopted to environmental changes.
