Question
During meiosis, homologous chromosomes exchange genetic material. This exchange of genetic material
Solution
The exchange of genetic material between homologous chromosomes during meiosis is known as crossing over. This process occurs during the prophase I stage of meiosis. Here are the steps:
-
Pairing of Homologous Chromosomes: During the early stages of prophase I, homologous chromosomes (one from each parent) come together and pair up in a process called synapsis.
-
Formation of Tetrad: The paired homologous chromosomes, each consisting of two sister chromatids, form a structure called a tetrad. This means there are four chromatids in close proximity.
