Epistasis The dominant action of a different chromosome or at a different locus on the same chromosome.

Etiolation The blanched condition produced in plants by the lack of light or by disease.

Etiology The sciene of the causes of disease.

Evapotranspiration Amount of water transferred into the atmosphere by evaporation from the soil surface and by plant transpiration

Exodermis The outermost cortial layer of the adult root.

Fat Vegetable oils, non-nitrogenous reserves in seeds or the volatile oils which perfume many flowers and leaves. (I wonder if you could add smell by increasing the fat?-karmaxul)

Gametophyte The phase in the life cycle of plants which bears the sex organs and gives rise to the gametes.

Gene The hereditary unit which controls the appearance of definite characters. The functional unit of heredity. A gene is a section of DNA that codes for a specific biochemical function in a living organism.

Genetic drift Random changes in gene frequency within a population resulting from sampling effects rather than natural selection, and hence of greatest importance in small populations.

Genome A complete haploid set of chromosomes as it is inherited from each parent, a genom.

Genotype 1. A group of individuals which are alike with respect to their hereditary factors.
2. The entire genetic constitution of an organism.
3. The single species upon which the genus is based.

Genus The principal subdivision of a family (plural: genera), a more or less closely related and definable group of plants comprised of one or more species. The generic name becomes the first word of the binomial employed in all member species.

Germ pore A pit on the surface of a spore membrane through which a germ tube makes its apperance. See illustration of pollen differentiation.
