What processes can disrupt gene linkage?

Crossing over can be the main cause of gene linkage disruption. The crossing of chromosomes in prophase 1 of meiotic division is called crossing over. If genes are located far from each other in the chromosome, then the probability of the formation of a cross between them is high and the percentage of formation of gametes with recombined genes is high, which means that more individuals with traits other than the parents are formed in the offspring. 1% crossing over is equal to the distance between genes on the same chromosome. Otherwise, this value is called another morganida.
