The question is incomplete as it does not have the options which are:

I. only

I. and II. only

II. and III. only

I, II, and III.

Answer:

I, II, and III.

Explanation:

The mechanism of natural selection can be explained for the trait which is determined by one gene but the traits which can be determined by more than one gene like height (polygenic trait), the selection becomes very complex.

The natural selection can be explained by the phenotype produced in a population and that depends on the genes.  The polygenic trait shows the variation in the population, therefore, it is impossible to predict only one mechanism and therefore all types of natural selection occurs on a population.

Thus,  I, II, and III are correct.

There are 3 types of bacteria that form tumor in different plant ares.

<em>Agrobacterium rhizogenes</em>,<em> Agrobacterium tumefaciens</em> strains contain either Ti or Ri plasmid but <em>Agrobacterium vitis</em> contain only Ti plasmid   which are virulent.

The transfer of T-DNA takes place into the body of host cells and then the DNA is expressed into the body of the host and thus forming gall or tumor.

While extrapolating, one </span>would usually estimate the unknown data with the presumption that existing trends in the known data will continue or that a current method will remain applicable.
