A gene duplication is a mutation that involves the repetition of a part of the chromosome.

What is a gene duplication?

Duplication is a genetic mutation that occurs when one or more nucleotides are repeated in the DNA sequence.

Characteristics of a gene duplication

  • This mutation occurs within the framework of DNA duplication, a miscrossover or a certain structural rearrangement can cause the disorder.

  • Duplications increase the number of genes in the gene pool, being a source of new genetic material and the basis for new evolutionary changes.

Therefore, we can conclude that duplications arise when a chromosomal segment is replicated more than once by mistake in DNA duplication.
