Genetic polymorphism of adult reindeer coat colour in a herding cooperative in Finnish Lapland

In a random sample of 188 adult reindeer belonging to a reindeer herding cooperative in Finnish Lapland, the following coat colour mutants were identified: Abf at the locus Agouti (A), kalppinokka (WNk) at the locus White Nose (WN) and white at the locus W (White). Coefficients of coat colour phenotypic polymorphism K were estimated, in order to quantify this genetic polymorphism. Estimations of K were 12.8% for the locus A (Agouti), 5.1% for the locus WN (White Nose), and 7.5% for the locus W (White). This polymorphism results probably from a change in fitness coefficient of genotypes carrying colour mutants following domestication in a random mating context which has not yet been proved

Reindeer coat colour variants in Finland

A research program based on reindeer coat colour had its first field survey in Finland after the calving season of May 2009. This short notice advances the main observations of the survey where, besides the wild allele, a new mutant could be identified, at least at three colour loci: Agouti (A), White Spotting (S) and White (W).Poron turkin värityypit SuomessaAbstract in Finnish / Lyhennelmä: Tutkimusprojekti poron turkin väreistä alkoi kenttätutkimuksilla Suomessa vasonnan jälkeen toukokuussa 2009. Tämä lyhyt tiedonanto osoittaa, että porolla on villialleelin lisäksi myös uusi mutanttialleeli vähintään kolmessa värilokuksessa: Agouti (A), Täplikäs (S) ja Valkoinen (W).Fargevarianter av reinpels i FinlandAbstract in Norwegian / Sammendrag: Et forskningsprosjekt begynte i felt etter kalving i 2009.
