Plant reproductive morphology be identical isospores or come in different sizes (microspores and megaspores), but strictly speaking, spores and sporophytes are neither male nor female because they do not produce gametes. The alternate generation, the gametophyte, produces gametes, eggs and/or sperm. A gametophyte can be monoicous (bisexual), producing both eggs and sperm or dioicous (unisexual), either female (producing eggs) or male (producing sperm). In the bryophytes (liverworts, mosses and hornworts), the sexual gametophyte is the dominant generation. In ferns and seed plants (including cycads, conifers, flowering plants, etc.) the sporophyte is the dominant generation. The obvious visible plant, whether a small herb or
Dominant white and for every trait, all animals inherit one allele from each parent. The original or "normal" form of "KIT", which is expected in horses without dominant white spotting, is called the "wild type" allele. Thus, a dominant white horse has one "KIT" allele with a mutation associated with dominant white spotting, and one wild type "KIT" allele. Dominant white horses were first described in scientific literature in 1912. Horse breeder William P. Newell described his family of white and near-white horses to researcher A. P. Sturtevant of Columbia University: "The colour of skin is white or so-called pink, usually with
