APA TEGESÉ APOGAMY ING BASA INGGRIS?
Apomixis
Ing botani, apomixis didefinisikan dening Hans Winkler minangka panggantos reproduksi seksual normal dening reproduksi aseksual, tanpa pembuahan. Dhéfinisi iki kayata ora nyebutaké meiosis. Mangkono "reproduksi aseksual normal" tanduran, kayata panyebaran saka cuttings utawa godhong, ora tau dianggep apomixis, nanging panggantos winih kanthi tanduran utawa ngganti kembang kanthi bulbil iku jinis apomixis. Anak-anak sing diprodhuksi apomisik sacara genetik identik karo tanduran induk. Sawetara penulis nyakup kabeh bentuk reproduksi aseksual sajrone apomixis, nanging generalisasi istilah kasebut wiwit mati. Ing tetanduran ngembang, istilah "apomixis" umum dipigunakaké sajroning pangertèn sing diwatesi tegesé agamospermy, yaiku klon reproduksi liwat wiji. Senajan agamospermi bisa sacara teoritis dumadi ing gimnosperma, katon ora ana ing grup kasebut. Apogamy minangka istilah sing padha karo macem-macem makna liwat wektu. Ing tetanduran kanthi gamétofit independen, istilah iki isih digunakaké bebarengan karo "apomixis", lan loro kasebut ngrujuk marang pambentukan sporofit dening partenogenesis sel gametofit.
Definisi saka apogamy ing bausastra Basa Inggris
Definisi apogamy ing kamus iku jinis reproduksi, sing dumadi ing sawetara pakis, ing ngendi sporofit berkembang saka gametofit tanpa campuran gametes. Definisi liya saka apogamy yaiku pangembangan sel diploid ing kanthong embrio tetanduran ngembang menyang embrio tanpa dibuahi.

In a similar way, a sporophyte may be produced from a gametophyte without any
union of gametes (apogamy). During natural conditions, these phenomena are
probably much less important than among pteridophytes. However, a wounding ...

Regarding the cause of apogamy, several explanations have been put forth.

A sporophyte, which is produced through apogamy, has the same chromosome
number as the gametophyte from which it is derived. Apogamy often occurs in

Fertilization which heralds the diploid or sporophytic phase, is a normal feature in
the life cycle of ferns and partly accounts for the typical alternation of generations.
