Verified step by step guidance1
Understand that meiosis is a type of cell division that reduces the chromosome number by half, creating four haploid cells, each genetically distinct from the parent cell.
Recognize that meiosis consists of two stages: Meiosis I and Meiosis II. Prophase I is a part of Meiosis I.
During Prophase I, homologous chromosomes pair up in a process called synapsis, forming structures known as tetrads.
Within these tetrads, a process called 'crossing over' occurs, where non-sister chromatids exchange segments of genetic material.
This exchange of genetic material during crossing over results in genetic recombination, contributing to genetic diversity in gametes.
