Continuous: height, weight, skin colour.

Discontinuous: eye colour, attached ear lobes

Continuous variation varies from degree to degree gradually, affected by external conditions. Discontinuous variation only has two or more definite 'extremes', determined by genes only.

Characteristics showing discontinuous variation fall into a few very distinct classes. The ability to roll the tongue, and blood groups, are examples of discontinuous variation.

These characteristics can be explained much more easily by simple rules of genetics and are not likely to be affected by other factors.

Discontinuous variation is characterized by either having the trait, or not having it, like Heart disease, or albinism.

Yes it is, because in discontinuous variation, the differences are clear cut and discrete, meaning that they will not merge/blend into each other.
