Question

Which condition would most likely result in an increase in the phenotypic variation within a population?

Answer 1

Answer:

The correct option is Option B i.e. a mutation that leads to individuals with genetic differences.

Explanation:

The phenotype is the morphological character of an organism. Phenotype of a species depend on the genetic characteristics of the species itself, because all the characteristics are actually results of the genetic setup of the species.

So, a change in the genotype of the organism can bring massive changes in its phenotype. These genetic modifications are made up by the mutations.

Answer 2

Answer: Option b

Explanation:

The increase in the genetic variation among the individual of species is due to mutation. The more the rate of mutation more will be the genetic variation in the population.

The mutation can be defined as a phenomenon in which a slight change in the base pair may produce an individual(with some variation in their body ) in the same species.

So, the reason of genetic variation is mutation.
