Zróżnicowanie genetyczne mieszańców międzygatunkowych lisów blue frost oraz ich form wyjściowych na podstawie sekwencji mikrosatelitarnych

The research objective was to determine differences in the genetic structure of the hybrids of Blue.Frost foxes and their original forms, i.e. the arctic fox and the silver fox. A multiplex PCR was.applied to five loci (FH2054, CPH3, FH2168, FH2164, FH2097). Sequences available from the.canine genome enabled the analogous loci to be amplified in both arctic foxes (blue and shadow).and silver foxes as well as in their hybridization crosses - Blue Frost foxes. The number of alleles,.the polymorphism information content, and the observed and expected heterozygosity differed.between the analysed animal groups. The highest PIC and heterozygosity values were noted for.the Blue Frost hybrids. The greatest genetic distance was found between the arctic shadow fox.and the silver fox. As expected, Blue Frost foxes turned out to be an intermediate form between.parental forms; accordingly, close genetic similarity values were reported between the hybrids and.the arctic blue and silver foxes.
