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.

No matter how it is born, a new gene starts its life as a single copy in the population.

As with any new mutation, by far the most likely outcome is that it will be lost by random drift or selection over the next few generations
