Recombination reshuffles alleles of two genes that lie on the same chromosome type, whereas independent assortment reshuffles alleles of two genes that lie on different chromosome types.
Explanation:
Alleles are two forms of same gene, they are located on the same loci of the homologous pair.
Recombination occurs when alleles from two homologous chromosomes get reshuffled during crossing over in meiosis.
Independent assortment refers to the tendency of alleles to be inherited independently from one generation to other.
