Mixtures of exons duplicated from genes with different functions can generate new genes with new functions, a process that is called exon shuffling.

Gene duplication happens on a massive scale when whole genome duplication occur. whole genome duplication are two type, 

1.Autopolyploid

2.Allopolyploid

Genetic exchange also happens between distantly related organisms by horizontal gene transfer, or HGT.

HGT is particularly important to prokarytotes and is the most common way by which they acquire new genes.

Intimacy between the genomes of the mitochondria and the nucleus within a cell, it may not be surprising that extensive HGT has occurred between them

Duplicate gene and its parental copy can subfunctionalize so that each carries out only some of the roles that the ancestral gene performed. 

Ex- a duplicate of the β-hemoglobin locus is expressed in the fetus.
