Horizontal Gene Transfer
Horizontal gene transfer (HGT) refers to the transfer of genes between organisms in a manner other than traditional reproduction. Also termed lateral gene transfer, it contrasts with vertical transfer, the transmission of genes from the parental generation to offspring via sexual or asexual reproduction. HGT has been shown to be an important factor in the evolution of many organisms, including bacteria, plants and humans.

Famous quotes containing the words horizontal and/or transfer:
“I am a sort of martyr, as you see,
A horizontal monument to patience.
The calves of waitresses parade about
My helpless head upon this sodden floor.
Well, I am down again, but not yet out.
O sweet frustrations, I shall be back for more.”
—Richard Wilbur (b. 1921)
“No sociologist ... should think himself too good, even in his old age, to make tens of thousands of quite trivial computations in his head and perhaps for months at a time. One cannot with impunity try to transfer this task entirely to mechanical assistants if one wishes to figure something, even though the final result is often small indeed.”
—Max Weber (1864–1920)
