Reakcijske norme za debelino hrbtne slanine pri testiranih mladicah v Sloveniji

Martina PLANINC, Milena KOVAČ, Špela MALOVRH

Povzetek


Živali imajo možnost, da se na razlike v okolju odzivajo različno. To imenujemo fenotipska plastičnost ali okoljska občutljivost. Robustne živali, ki kažejo majhno variabilnost med okolji, so manj občutljive. Namen prispevka je z reakcijskimi normami preučiti interakcijo med genotipom in okoljem za debelino hrbtne slanine. Za analizo podatkov smo uporabili model z naključno regresijo, reakcijske norme smo napovedali 239 očetom. Rezultati kažejo, kako se preučevana lastnost za posameznega očeta skozi okolja spreminja.

Ključne besede


prašiči; mladice; genetika; okolje; maternalni genotip; debelina hrbtne slanine; reakcijske norme; Slovenija
