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 white spotted coat. Dominant white is genetically distinct from Sabino and both genetically and visually distinct from gray and cremello. Dominant white is not the same as lethal white syndrome, nor are dominant white horses "albinos". Tyrosinase negative albinism has never been documented in horses. Some forms of dominant white are thought to result in nonviable embryos when a zygote has two "W" alleles (is homozygous). However, this has not been verified for all dominant white genetic variations. Dominant white horses are born with pink skin and a white coat, which they retain throughout their lives. Although the term "dominant
