The process of speciation:


The process of speciation:

It is the formation of a new species.

Speciation is the process of the formation of new species. The gene pools of two populations reproductively isolated or separated from each other to form two new species.

Reproductive isolation:

Reproductive isolation happens when two populations cannot interbreed and form a fertile offspring. Reproductive isolation can produce through geographic or behavioural or temporal isolation.

Behavioural isolation:

It occurs when populations have other behaviors or different courtship rituals involved in reproduction.

Geographic isolation:

It is related to the geographic location of the populations. It occurs when populations are isolated by geographic barriers, such as forests, mountains, or rivers.

Temporal isolation:

It is related to time. It occurs when populations reproduce at different times.

Species: we can define species as a group of individuals living in one or more populations that can interbreed to produce fertile and healthy offerings.

Species are distinct from one another by postzygotic and prezygotic barriers. These barriers maintain the reproductive isolation of species. It keeps different organisms from mating to give birth to fertile offspring after and before the formation of zygote.

New species produced by speciation are genetically distinct descendent populations. Speciation involves the reproductive isolation of groups within the original population and the accumulation of genetic differences between the two groups.

The process of speciation:

There are two main kinds of speciation, namely, allopatric and sympatric speciation.

Allopatric speciation:

In this type of speciation, groups of animals become reproductively isolated and diverge because of a geographical barrier.

In sympatric speciation:

In this type of speciation, reproductive isolation and divergence occur without any geographical barriers such as by polyploidy.
