Horizontal gene transfer refers to the transfer of genetic material through a mechanism other than reproduction. This mechanism is a common source of new genes in prokaryotes, sometimes thought to contribute more to genetic variation than gene duplication. It is a common means of spreading antibiotic resistance, virulence, and adaptive metabolic functions. Although horizontal gene transfer is rare in eukaryotes, likely examples have been identified of protist and <answer>alga genomes containing genes of bacterial origin</answer>.
What is one example of horizontal gene transfer in eukaryotes?
alga genomes containing genes of bacterial origin
