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.

Chromosomal crossover, or crossing over, is the exchange of genetic material during sexual reproduction between two homologous chromosomes ' non-sister chromatids that results in recombinant chromosomes. It is one of the final phases of genetic recombination, which occurs in the pachytene stage of prophase I of meiosis during a process called.

Početkom anafaze I, upareni homologni hromosomi se razdvajaju, a svaki od njih nosi razmijenjeni segment (putem krosing overa) svog.
