Meiosis I. Meiosis is preceded by an interphase consisting of G 1, S, and G 2 phases, which are nearly identical to the phases preceding mitosis. The G 1 phase (the “first gap phase”) is focused on cell growth. During the S phase—the second phase of interphase—the cell copies or replicates the DNA of the chromosomes. Finally, in the G 2 phase (the “second gap phase”) the cell

Crossing over is the exchange of genetic material between non-sister chromatids of homologous chromosomes during meiosis, which results in new allelic combinations in the daughter cells. Each diploid cell contains two copies of every chromosome, one derived from the maternal gamete and the other from the paternal gamete.

Crossing over is important for the normal segregation of chromosomes during meiosis. [2] Crossing over also accounts for genetic variation, because due to the swapping of genetic material during crossing over, the chromatids held together by the centromere are no longer identical.

During Which Stage Of Meiosis Does Crossing Over Occur
Crossing over is important for the normal segregation of chromosomes during meiosis. [2] Crossing over also accounts for genetic variation, because due to the swapping of genetic material during crossing over, the chromatids held together by the centromere are no longer identical.
Chromosomes segregate during Meiosis I and you might expect that all genes on a chromosome would be inherited as a unit. However, during prophase I homologous chromosomes pair up and become attached to one another. At this time, crossing over moves sections of DNA between homologous chromosomes and allows for independent assortment.
Why is crossing over an important factor in meiosis? – Quora
Crossing over occurs only during prophase I. The complex that temporarily forms between homologous chromosomes is only present in prophase I, making this the only opportunity the cell has to move DNA segments between the homologous pair. Meiosis does not occur in all cells.

Topic 10.1: Meiosis – AMAZING WORLD OF SCIENCE WITH MR. GREEN
Meiosis is a process where germ cells divide to produce gametes, such as sperm and egg cells. In prophase I of meiosis, chromosomes condense and homologous recombination takes place, leading to genetic variation through chromosomal crossover. This forms a tetrad, which is made up of four chromatids (two sister chromatids per chromosome).
