Genetic diversity and Population genetics An individual organism's phenotype results from both its genotype and the influence from the environment it has lived in. A substantial part of the phenotypic variation in a population is caused by genotypic variation. The frequency of one particular allele will become more or less prevalent relative to other forms of that gene. Variation disappears when a new allele reaches the point of fixation —when it either disappears from the population or replaces the ancestral allele entirely.
To Jenkins' Spoiler-Laden Guide to Isaac Asimov Introduction Though perhaps best known throughout the world for his science fiction, Isaac Asimov was also regarded as one of the great explainers of science.
His essays exemplified his skill at making complex subjects understandable, and were written in an unformal style, liberally sprinkled with personal anecdotes that endeared him to a legion of faithful readers.
It was all a Evolution and humans essay of love; in particular Asimov often remarked that of all his writing, his essays for The Magazine of Fantasy and Science Fiction were his favorite, despite the fact that he received the lowest word-rate payment for them.

Please note that the emphasis is on known, since there are undoubtedly some we have missed.
We have included every essay that has appeared in Asimov's collections, as well as a good number of those that have never been collected.
Also included are introductions Asimov wrote for other books, though in this department we probably have missed quite a few.
Notes on the listings There are some essays that do not appear in any collection and are not readily available, so that the authors haven't read them yet. For those essays the subject field is left blank.
That list is ordered alphabetically according to the title of the essay, and includes a designation of the collection in which each essay appears as well as a very brief subject description for each essay.
We have used those descriptions, but have added to them in some places, as well as added our own descriptions for essays published since his list appeared.
