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.
