Pasmina

Pasmina je specifična grupa domaćih životinja koje imaju homogen izgled (fenotip), homogeno ponašanje i/ili druge karakteristike koje je razlikuju od drugih organizama iste vrste. U literaturi postoji nekoliko neznatno odstupajućih definicija.^[2]^[3] Rase se formiraju genetskom izolacijom i prirodnom adaptacijom na životnu sredinu ili selektivnim uzgojem, ili kombinacijom ovo dvoje. Uprkos centralnom značaju ideje „pasmine“ u stočarstvu i poljoprivredi, ne postoji jedinstvena, naučno prihvaćena definicija pojma.^[4]^:340 Teorijskim razmatranjima je pokazano da je za pojam pasmina postoji beskonačan broj različitih različitih definicija, koje manje-više ispunjavaju uobičajene zahteve koji se nalaze u literaturi.^[3] Rasa stoga nije objektivna ili biološki proverljiva klasifikacija, već je umesto toga žargonski termin među grupama odgajivača koji dele konsenzus oko toga koji kvaliteti čine neke pripadnike date vrste članovima određene podgrupe.^[5]

Druga tačka gledišta je da je rasa dovoljno konzistentna po tipu da se logički grupiše i kada se pari unutar grupe proizvodi isti tip.^[6] Kada se uzgajaju zajedno, individue iste rase prenose ove predvidljive osobine na svoje potomstvo, a ova sposobnost – poznata kao „pravi uzgoj“ – je uslov za pasminu. Biljne pasmine su poznatije kao kultivari. Potomstvo proizvedeno kao rezultat uzgoja životinja jedne pasmine sa drugim životinjama druge pasmine je poznato kao melezi ili mešanci. Ukrštanja između životinjskih ili biljnih varijanti iznad nivoa pasmine/kultivara (tj. između vrsta, podvrsta, botaničkih varijeteta, čak i različitih rodova) se nazivaju hibridi.^[7]

U biološkoj taksonomiji, pasmina je neformalni rang u taksonomskoj hijerarhiji za koji postoje različite definicije. Ponekad se to koristi da se označi nivo ispod nivoa podvrste, dok se u drugim slučajevima koristi kao sinonim za podvrstu.^[8] Korišćena je kao viši rang od soja, pri čemu nekoliko sojeva koji čine jednu pasminu.^[9]^[10] Pasmine mogu biti genetski različite populacije individua unutar iste vrste,^[11] ili se mogu definisati na druge načine, npr. geografski, ili fiziološki.^[12] Genetska izolacija između pasmina nije potpuna, ali su se možda nakupile genetske razlike koje (još) nisu dovoljne da se razdvoje vrste.^[13]

Mnogi izvori prepoznaju ovaj termin, mada njega ne reguliše nijedan od formalnih kodeksa biološke nomenklature. Taksonomske jedinice ispod nivoa podvrste se obično ne primenjuju na životinje.^[14]

Oplemenjivanje: selekcija po uzgajivačima[uredi | uredi izvor]

Ovaj primer pokazuje tri različite rase domaćih svinja, koje se veoma razlikuju po izgledu.

Uzgajivač (ili grupa odgajivača) koji u početku uspostavljaju rasu to čine odabirom pojedinačnih životinja iz genskog fonda za koje vide da imaju neophodne kvalitete potrebne za poboljšanje modela rase kojem teže. Ove životinje se nazivaju temeljnim fondom. Štaviše, odgajivač pari najpoželjnije predstavnike rase sa svoje tačke gledišta, sa ciljem da takve karakteristike prenese na njihovo potomstvo. Ovaj proces je poznat kao selektivni uzgoj. Pisani opis poželjnih i nepoželjnih predstavnika rase se naziva standardom rase.

Karakteristike rase[uredi | uredi izvor]

Specifične karakteristike rase, poznate i kao osobine rase, su nasleđene, a čistokrvne životinje prenose takve osobine iz generacije u generaciju. Dakle, svi primerci iste rase nose nekoliko genetskih karakteristika originalnih osnovnih životinja. Da bi zadržao rasu, odgajivač bi izabrao one životinje sa najpoželjnijim osobinama kako bi postigao dalje održavanje i razvoj takvih osobina. U isto vreme, rasa bi izbegavala životinje koje imaju karakteristike nepoželjne ili nisu tipične za rasu, uključujući greške ili genetske defekte. Populaciju u okviru iste rase treba da čini dovoljan broj životinja za održavanje rase u okviru navedenih parametara bez potrebe prinudnog inbridinga.

Domaće rase životinja se obično razlikuju od zemlje do zemlje i od nacije do nacije. Rase koje potiču iz određene zemlje poznate su kao „domaće rase” te zemlje.
