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 allows for ... Crossing-over allows the reassortment of linked
Crossing over of genes is a big factor in the genetic diversity of living things. Here
we will define the process of crossing over, and further...
The idea that intrachromosomal recombinants were produced by some kind of
exchange of material between homologous chromosomes was a compelling one.
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.
