Results from the interaction of a number of gene loci specifying a given trait. rather than stepwise inheritance patterns, phenotypic distributions are more curve-like.

continuous variation

Explanation:

Variation is the differences between individuals within a species. Variation could be caused by genetic inheritance or by environment factor(s). There are two types of variation which are; continuous variation and discontinuous variation.

''CONTINUOUS VARIATION results from the interaction of a number of gene loci specifying a given trait. Rather than stepwise inheritance patterns, phenotypic distributions are more curve-like.'' Examples of continuous variation are; skin colour, air colour, height and weight.

the organisms are not adapted to live in some communities or habitats.

a "theory" a suggestion that is not 100 % accurate, or a figure. some people say its a theory because they of all the passed theory's about one subject. it depends sometimes theory might be accurate and sometimes they are.
