Guida verificata passo dopo passo1
Understand that meiosis consists of two successive divisions: meiosis I and meiosis II.
Recall that each division has its own prophase stage, named prophase I and prophase II respectively.
Recognize that prophase I occurs during the first meiotic division and is characterized by homologous chromosomes pairing and crossing over.
Note that prophase II occurs during the second meiotic division and involves the preparation of chromosomes for the second division without further DNA replication.
Conclude that since there are two meiotic divisions, prophase occurs twice: once in meiosis I and once in meiosis II.
