Question

geographical and reproductive isolation of organisms leads to speciation

Answer 1

Answer:

• Speciation is the formation of distinct species in the course of evolution.

• It involves splitting of a single evolutionary lineage into two or more genetically independent lineages.

• Speciation occurring due to geographic isolation of two population is known as Allotropic speciation.

• It happens when a population is separated by mountains or land masses thus preventing crossbreed in between the two populations.

• This leads to barriers to gene flow hence evolution occurs and thus speciation takes place.

Answer 2

Answer:

Explanation:

(i) Species is the group of organisms that can produce fertile individuals through natural reproduction.

(ii)   Each species grows in specific geographical condition. Their food, habitat, reproductive ability

and period is different.

(iii) Along with genetic variation, geographical and

reproductive changes are responsible for formation of new species.

(iv) Hence, geographical and reproductive isolation

leads to speciation.
