What is horizontal gene transfer?
Quick Answer
Horizontal gene transfer is the movement of genes between organisms without parent-to-offspring inheritance. In bacteria, it helps spread traits like antibiotic resistance very quickly.
The Full Story
Unlike ordinary inheritance, horizontal gene transfer moves genetic material between unrelated cells, often across the same generation. In bacteria, it happens mainly by transformation, transduction, or conjugation. This process can rapidly spread genes for antibiotic resistance, virulence, or new metabolic pathways. It is one reason bacteria can adapt so quickly to changing environments and medical treatments.
