Reproductive isolating mechanisms return is rim in turn denotes the isolating mechanisms which in turn prevent the reproduction among species and this in turn can be of two different types that is it can be pre -mating and it can be post -mating that is the one which in turn avoids mating and the one that can occur after mating respectively so with regard to pre -mating this intern can be of four different types the first one in turn includes the temporal isolation.
00:32
So with regard to the term being temporal, here this intern can have different planes.
00:37
For example, let's say one species in turn can be active at day, whereas the other species intern is found to be active at night.
00:44
So this intern explains the temporal mechanism and followed by other one which is called us the ecological.
00:51
Ecological intern denotes that one species can live in one particular habitat, let's say a and the other one can live in another particular habitat b.
00:59
So this intern can lead to one type of isolation.
01:03
And then the third one is in turn referred to be as the behavior oral.
01:06
So the preference in turn can differ among the species.
01:10
So this intern is intern denoted as behavior oral.
01:14
And then the last one is in turn denoted as mechanical.
01:18
Here mechanical intern denotes that the copulation tends to happen but the transfer of the sperm intern doesn't happen.
01:25
Here this intern denotes the mechanical.
01:27
So this these are the ones which are intern denoted with pre.
01:31
The one which intern would come under pro post -mating intern denot, the first one that is called as the gametic incompatibility, return as gi...
