How does crossing over incrase phenotypicvariation in a population?

crossing over allows new genes to be made by the crossing over itself or by mutations that occur in the genes as crossing over occurs. since the phenotype is the physical appearance of the gene, the crossing over can change the genotype which can change the phenotype.
