Assertion In intraspecific speciation, a single species may give rise to new species
Reason Gene flow within the populations must be interrupted

Assertion : Prolonged intraspecific competition causes an increases in the size of the niche of a population. Reason : In such a population, use of a new type of resource will increase through the generations.

Variations giving rise to new species are serialised by the process of

Assertion : Tiger is rare species . Reason : Tiger population is very small .

Assertion : Tiger is a rare species. Reason : Tiger population is very small.

Assertion : Formation of new species is called speciation. Reason : The deme has a common gene pool.

The number of genes of a specific trait within the population of a species shows

An evolutionary process, giving rise to new species adapting to new habitat and ways of life is called
