The Darwinian variations are

Assertion :- Any population has built in variation in characteristics. Reason :- Variations are always stable and inheritable.

Assertion: Mendelian disorders are transmitted to offspring on the same lines as in the principles of inheritance. Reason: The pattern of inheritance of Mendelian disorders cannot be traced in a family by the pedigree analysis.

Assertion: Evolution is adaptation through generations. Reason: Only useful and continuous variations are inheritable.

Which one provides correct sequence of events in origin of species according to Darwinism ? 1. Natural selection 2. Variations and their inheritance ? 3. Survival of fittest 4. Struggle for existence

Given : 1 = Natural selection , 2 = Variations and their inheritance , 3 = Survival of the fittest , 4 = struggle for existence According the Darwinism, which of the following represents the correct squence of events in the origin of new species ?
