Crossing over results in the exchange of genetic material, which occur...
Crossing over occurs between prophase 1 and metaphase 1 and is the process where homologous chromosomes pair up with each other and exchange different segments of their genetic material to form recombinant chromosomes. It can also happen during mitotic division, which may result in loss of heterozygosity.

Crossing over in Meiosis
Crossing over is the exchange of genetic material between homologous chromosomes during meiosis. This process is important in creating genetic diversity in offspring.
Non-sister chromatids of the homologous chromosomes
During prophase I of meiosis, homologous chromosomes pair up to form bivalents. Within each bivalent, the non-sister chromatids of the homologous chromosomes can exchange genetic material through a process called crossing over. This results in the formation of new combinations of alleles on the chromosomes.
Significance of Crossing Over
Crossing over is significant for the following reasons:
- Genetic diversity: Crossing over results in the formation of new combinations of alleles on the chromosomes. This leads to genetic diversity in the offspring, which is important for the survival of a species.
- Linkage: Crossing over can also break the linkage between genes that are located close to each other on a chromosome. This allows for the independent assortment of genes during meiosis, which further increases genetic diversity.
Conclusion
Crossing over occurs between the non-sister chromatids of the homologous chromosomes during meiosis. This process is important for creating genetic diversity in offspring and breaking the linkage between genes on a chromosome.
