Short note on meiosis

SpletMeiosis is a special type of cell division in which the genetic material or the number of chromosomes is reduced to half to form gametes for sexual reproduction. Meiosis in … SpletThe prophase I of meiosis occurs in the following stages: 1. Leptotene- This phase is the start of prophase-I. It is marked by the condensation of the chromosomes. 2. Zygotene- In this phase the homologous chromosomes start pairing up, called the synapsis. The synaptonemal complex starts building up.
