The DAPI staining of chromosomes of P. xanthopygus revealing: a Heteromorphic pair 7, female from Malargüe, the south of Mendoza b Homozygous metacentrics of male from the north of Mendoza c Homozygous metacentrics of female from Catamarca Province d Heterozygous pair 3 in male from Jujuy. In boxes are the heteromorphic pairs e Details of pairs involved in the chromosome polymorphisms described in this work: e)1 pair 7 from south Mendoza population, e)2 pair 7 from north of Mendoza, e)3 pair 3 from Catamarca, e)4 pair 3 from Jujuy, the size of chromosomes was modified for a better comparison of DAPI bands. Bar = 10 µm.
