WebExplicación muy detallada del proceso de meiosis. Diferencias entre mitosis y meiosis. WebMeiosis follows a similar pattern, but with two rounds of cell division. The first round, known as meiosis I, involves the separation of homologous chromosomes (chromosomes that are similar in shape and size). The second round, meiosis II, involves the separation of sister chromatids (copies of the chromosomes produced during DNA replication).

WebProphase I is further divided into sub-stages: Leptotene: In this stage, the initiation of chromosome condensation takes place and it attains a composite form. Zygotene: In this, the homologous chromosomes pairs, the process is called chromosomal synapsis. It is followed by the generation of a composite composition called the synaptonemal complex.
