Chromosomal crossover (or crossing over) is the exchange of genetic material
between homologous chromosomes that results in recombinant chromosomes ...
At this time, crossing over moves sections of DNA between homologous
chromosomes and ... Crossing over during meiosis allows recombination of
This ensures genetic variation in sexually reproducing organisms. Further
genetic variation comes from crossing over, which may occur during prophase I
Crossing over, or recombination, is the exchange of chromosome segments ...
Crossing over creates new combinations of genes in the gametes that are not ...
Each chromatid contains a single molecule of DNA. So the problem of crossing
over is really a problem of swapping portions of adjacent DNA molecules.
