The sizes of genomes has increased over evolutionary time, with extra genetic material providing raw material for geneticdiversification. Errors during meiosis due to unequal crossing over during Prophase 1 can lead to duplication. Slippage during DNA replication can result in deletion or duplications.

ANSWER:-
Gene duplications can arise as products of several types of errors in DNA replication and repair machinery as well as through fortuitous capture by selfish genetic elements. Common sources of gene duplications include ectopic recombination, retrotransposition event, aneuploidy, polyploidy, and replication slippage.
