Explain the DNA Hybridisation?

This technique is used to study or compare the genetic affinity between two organism. In such studies the deoxyribonucleic acid (DNA) of both organisms is extracted. Then the DNA strand of  both of them are separated, After this the single strand of each organism is made to come in contact with each other in vitro, in order to unite or hybridise them.

The extent to which this union occurs i.e. the degree of hybridisation is an indicator of the closeness or distantness of the two organisms. Table  shows the use of this technique in estimating the genetic similarities among some vertebrates.

DNA matching or hybridisation technique holds great promise in solving taxonomic problems. However, incomplete fossil records in many animals may make it difficult to solve all evolutionary or phylogenetic relationships by this method.
