The second generation was the one that was allowed to self pollinate
When Charles Darwin stepped ashore on the Galapagos Islands in September 1835, it was the start of five weeks that would change the world of science, although he did not know it at the time. Among other finds, he observed and collected the variety of small birds that inhabited the islands, but he did not realize their significance, and failed to keep good records of his specimens and where they were collected.
The answer is morph.

at the same time and belong to a panmictic population (one with random mating).
