Gene duplication

Explanation:

Gene duplication is an evolutionary process that includes different phenomena such as, among others, unequal crossover, chromosome rearrangement, chromosome duplication, etc. These duplicated genes are redundant in function and therefore they may accumulate mutations such as insertions or deletions at higher rates compared to single-copy DNA sequences, thereby producing homologous genomic fragments with different lengths

Dylan Summers · Answer 2

They was likely a gene duplication

Explanation:

Evolutionary divergence tends to follow gene duplications, as variations in genes or mutation in one gene are no longer taken against as strongly so the individual gets a copy of a functional gene.
