Ukwabelana ngesondo

Livela

Isini luphawu olugqibayo enoba into evelisa iintlobano zesini ivelisa iigamete zenkunzi okanye zamabhinqa . [1] [2] Izityalo zamadoda kunye nezilwanyana zivelisa i-gametes encinci ehambayo (i-spermatozoa, i-sperm, i-pollen ), ngelixa abafazi bavelisa ezinkulu, ezingenayo i-motile ( i-ova, edla ngokubizwa ngokuba ngamaseli eqanda). [3] Izinto eziphilayo ezivelisa zombini ezi ntlobo zezilwanyana zibizwa ngokuba zii <em>hermaphrodites . [2] [4] Ngexesha lokuzala, iigametes zamadoda nabasetyhini ziyadibana ukuze zenze ii-zygotes, ezikhula zibe yinzala efumana iimpawu kumzali ngamnye.

Amadoda kunye nabasetyhini beentlobo banokuba nokufana komzimba (i-monomorphism yesondo) okanye iyantlukwano (i- sexual dimorphism ) ebonisa iingcinezelo ezahlukeneyo zokuzala kwisini esahlukileyo.

kodwa ukuba isondo asinayo iincopho ezijoliswe ekuzaleni, ngoko ke &egrave; ngokuchasene nemvelo kwaye &egrave; ngoko ke isenzo esingcolileyo.

Sexual reproduction requires both male and female haploid gametes. In most species, these gametes are produced by individuals that are either male or female. Species that have male and female members are called dioecious (from the Greek for 'two houses'). In some species, a single individual may possess both female and male reproductive systems. Such species are called monoecious ("one house") or hermaphroditic."  Unknown parameter |vauthors= ignored (help); Unknown parameter |url-status= ignored (help)
