Horizontal Transfer. Horizontal gene transfer is known to occur between different species such as between prokaryotes organisms whose cells lack a defined nucleus and eukaryotes organisms whose cells contain a defined nucleus and between the three dna containing organelles of. And when the gene is passed on from parental organism to its own progeny it is said to be vertical.
Horizontal gene transfer hgt is arguably the most conspicuous feature of bacterial evolution. I have been drawing our regulators attention to it at least since 1996 1 when there was already sufficient evidence to suggest that transgenic dna in gm crops and products can spread by being taken up directly by viruses and bacteria as well as plant and animals cells.

This can occur both between bacteria of the same species and between different species and by several different mechanisms given the right conditions. Horizontal gene transfer hgt or lateral gene transfer is any process in which an organism gets genetic material from another organism without being the offspring of that organism. Also known as lateral gene transfer is the non sexual movement of genetic information between genomes. Horizontal gene transfer is one of the most serious if not the most serious hazard of transgenic technology.
