Crossing Over YouTube
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.
