Origin of apogamy¹

First recorded in 1875–80; apo- + -gamy

For the sake, however, of securing more descriptive terms, I will coin the words Apogamy and Homogamy.

Apogamy, of course, answers to indiscriminate isolation, or separate breeding.

In the former case there arises Homogamy, and in the latter case there arises Apogamy.

Other names for indiscriminate isolation are separate breeding and apogamy.

Isolation, then, is a genus, of which Apogamy and Homogamy are species.
