Method of creating variation in asexually propogated crop is

The method of creating variation in asexually propagated crops is Polyploidy.
The fusion of two or more genomes within one nucleus results in polyploidy, resulting in each cell containing more than two pairs of homologous chromosomes.
Polyploidy occurs in the majority of angiosperms and is important in crops that humans depend on for survival at the same time it serves as the method of creating variation in asexually propagated crops.
