All dissimilarities of characters between members of same species are called variations.
The heritable variations form the 'raw material' for evolution.

What forms the raw materials for evolution?

Which variations from raw materials of organic evolution ?

According to neo-darwinism, variations which are the raw material of evolution occur

The cross pollination between the same species is also called

The presence of differences between organisms of the same species is called

Discontinuous variation is also called quantitative inheritance. Continuous variation is also called qualitative inheritance. Variation is the raw material for evolution. Variation provides genetic material for natural selection.

Can non-heritable variations lead to evolution? Explain in brief.

Can non-heritable variations lead to evolution? Explain in brief.

The competition for food and between the members of same species is called interspecific competition.

Variation between different species is always------the variation within a species
