Summary Introduction
To review:
The three types of genetic transfer and discuss the one which is more likely to occur between the members of different species and the potential consequences of interspecies genetic transfer.
Introduction:
Genetic recombination is characterized by DNA (deoxyribonucleic acid) transfer in bacteria from one organism called donor to another organism called recipient. Such a type of genetic transfer is also known as horizontal gene transfer. It refers to the genetic matter is the movement of genes between two microbes and is a crucial aspect in the evolution of various organisms.
