Mechanical isolation in biology is a type of reproductive barrier that prevents mating from happening between two organisms. Organisms may attempt to mate, but physical barriers between genital connection prevent mating from occurring. What are some examples of behavioral isolation? Some examples of beha...
evolution: new speciesThere are many hypotheses about how speciation starts, and they differ mainly in the role of geographic isolation and the origin of reproductive isolation (the prevention of two populations or more from interbreeding with one another). ...
Reproductive isolation means that members of different species cannot interbreed and produce viable offspring. This can be pre-zygotic or post-zygotic, meaning before or after fertilization. Biology: High School 29chapters |238lessons|9flashcard sets ...
Zoology, branch of biology that studies the members of the animal kingdom and animal life in general. It includes both the inquiry into individual animals and their constituent parts, even to the molecular level, and the inquiry into animal populations,
According to "Molecular Biology of the Cell": Only about one nucleotide pair in a thousand is randomly changed every 200,000 years. Even so, in a population of 10,000 individuals, every possible nucleotide substitution will have been "tried out" on about 50 occasions in the course of a mi...
Reproductive isolation means that individuals from two groups are unable to interbreed successfully, that is, produce healthy, fertile offspring. So according to this definition, an individual is a member of a particular species if it can breed successfully with members of that species but not with...

This concept was given byErnst Mayr. It is also called the reproductive isolation concept. It is stated that a species is a group of natural populations that interbreed among themselves (actually or potentially) but don’t do the same with other groups as they are“reproductively isolated”from...
The equilibrium theory of island biogeography proposed by MacArthur and Wilson posits that species diversity on an island will be positively impacted by island area and negatively impacted by isolation, which has been confirmed for the Channel Islands. In this study, we have extended MacArthur and ...
