The process in which related dna sequences from two different sources are exchanged is called

Answer: Homologous Recombination

Explanation:

In DNA recombination, homologous recombination is a type of gene repair in which nucleotide sequences are exchanged between two identical molecules of DNA.

When DNA damages occur such as DNA double-stranded breaks or DNA gaps during DNA synthesis.

To conserve genome, cells uses a homologous recombination (HR), a type of DNA repair.

In genetic engineering a foreign DNA with identical nucleotide sequence similar to that of the missing DNA gaps or breaks are introduced into a target cell. The cell recognizes the identical DNA sequences as homologues, causing target gene to be exchanged with the foreign DNA sequence during DNA repair.

HR also occur naturally.
