Crossing Over Definition

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. These pairs of chromosomes, each derived from one parent, are called homologous chromosomes. When diploid organisms undergo sexual reproduction, they first produce haploid gametes through meiosis. During prophase I of meiosis, homologous chromosome align with each other and exchange genetic material, so that some of the resultant chromosomes are recombinants – containing a mixture of genes derived from the maternal as well as the paternal chromosomes.
