Question

There would be no evolution if
(a) the inheritance of acquired characters did
not take place
(b) somatic variations were not inheritable
(c) genetic variations were not found among
members of population
(d) somatic variations would not transform into
germinal variations

Answer 1

There would be no evolution if genetic variations were not found among members of population.

* These genetic variations within a species are then passed on to the next generation and thereby evolution occurs.

* Genetic variation is the driving force for natural selection to take place as it moderates the allele frequency accordingly.

* It allows the survival a particular group due to 'survival of the fittest', thereby maintaining the evolution of the new traits or characters.

* Genetic variation can take place because of the following reasons:

1.  Mutation-  can give rise to new alleles

2. Random fertilization

3. Random mating

4. Recombination during crossing over in meiosis.

Answer 2

(c) genetic variations were not found among  members of population

Explanation:

Evolution is the process through which population of organism changes over generations, through which new species can arise. It is a natural process. Genetic  mutation is the main reason of evolution, which is necessary  for the evolution of new species. if  genetic variations were not found among  members of population, then there would be no evolution.
