Isolation - Isolation is the segregation or separation of populations by certain barriers, which prevent interbreeding. As a result gene flow between populations is prevented. Each population on isolation, develops genetic divergence independently leading to the format..

Reproductive Isolation - Reproductive isolation is the inability of members of different species to interbreed in natu..

The physiological differences between individuals may also sometimes bring about isolation..

It is the isolation brought about by genetically determined agency, which prevents interbreeding. Following are the various mechanisms by which reproductive isolation can be brought abou..

A system, which can neither exchange mass nor energy with surroundings, is called an isolated system. They are also called insulated systems. Hot coffee (in contact with its vapour) in a closed and insulated thermos is an example of isolated system. Since the vessel i..

It is the isolation in space of the two populations of the same species, due to geographical barriers such as the sea, deserts, mountains and rivers, for land plants and animals. Geographical isolation plays an important role in 'allopatric speciation'. Allopatric species are t..

It is the situation where after mating, fertilization fails to occur due to differences in the chromosomal numbe..

Methods to Determine Order of a Reaction - For determination of the order of a reaction, following methods are usually employed. a) Graphical Method b) Initial Rate Method c) Ostwald Method of Isolation..
