Question

The distribution of most phenotypic variation in most species may be described as...

A. coming in discreet clusters.

B. a continuum of gradual change.

C.being specifically geared to certain environmental conditions

D. completely random with little or no regularity

Answer 1

Option 'C' (being specifically geared to certain environmental conditions) is correct

Justification: The distribution of most phenotypic variation in most species known as 'population variation', is influenced by a number of factors which includes the genetic structure of population and and the environmental conditions. So, this option is correct.

Justification for incorrect options:

• Option 'A' is incorrect because the distribution of phenotypic variation in most species will not come in discrete clusters as the alleles of one gene will always be found in one chromosomal position.
• Option 'B' is incorrect because the distribution of most phenotypic variation in most species is not a continuum of gradual change.
• Option 'D' is incorrect because the distribution of most phenotypic variation in most species is not random.
