Erkak

Erkak ( belgisi:♂) - urug'lanish jarayonida kattaroq urg'ochi gameta ^[1]^[2]^[3] yoki tuxumhujayra bilan birikadigan sperma deb nomlanuvchi gameta ( jinsiy hujayra) hosil qiluvchi organizmning jinsi.

Erkak organizmi ayolning kamida bitta tuxum hujayrasiga ega bo'lmasdan jinsiy yo'l bilan ko'paya olmaydi, lekin ba'zi organizmlar ham jinsiy, ham jinssiz yo'l bilan ko'payishi mumkin. ^[4] Aksariyat erkak sutemizuvchilar, shu jumladan erkak odamlarda Y xromosomasi mavjud ^[5]^[6] bu erkak jinsiy a'zolarini rivojlantirish uchun ko'proq miqdorda testosteron ishlab chiqarishni kodlaydi. Hamma turlar jinsni aniqlashning umumiy tizimiga ega emas. Ko'pgina hayvonlarda, shu jumladan odamlarda jins genetik jihatdan aniqlanadi; biroq, Cymothoa exigua kabi turlar yaqin joyda mavjud bo'lgan urg'ochilarning soniga qarab jinsini o'zgartiradi. ^[7]

Odamlarda erkak so'zi gender roli yoki gender o'ziga xosligining ijtimoiy ma'nosida jinsga murojaat qilish uchun ham ishlatilishi mumkin.
