Verified step by step guidance1
Understand that genetic recombination, also known as crossing over, is a process where homologous chromosomes exchange genetic material.
Recall that meiosis is divided into two main stages: Meiosis I and Meiosis II, each with its own phases: prophase, metaphase, anaphase, and telophase.
Focus on Meiosis I, specifically prophase I, where homologous chromosomes pair up in a process called synapsis, allowing crossing over to occur.
Recognize that genetic recombination typically occurs during prophase I of meiosis, as this is when homologous chromosomes are closely aligned and can exchange genetic material.
Note that while other phases like metaphase I and II involve chromosome alignment and separation, they do not involve genetic recombination.
