Assertion: Disruptive selection changes the population towareds one particular direction.
Reason: This type of selection favours average sized individuals.

Directional selection favour :

Assertion Disruptive selection is the rarest form of selection Reason Disruptive selection leads to speciation

Differentiate directional and disruptive selection.

Disruptive selection is rarest form of selection: Give reason.

Assertion : Natality rate increases the population size and population density both. Reason : Natality increase the number of individuals in an area by births.

Explain stabilizing, directional and disruptive selection with examples.

Assertion Directional selection operates in response to gradual changes in enviromental conditions Reason Stabilising selection operates when phenotypic features coincide with the optimal environmental conditions

Assertion: Population ecology is a link of ecology to population genetics and evolution. Reason: Natural selection operates at population level to evolve the desired traits.
