Similar relationships associated with karyotype were
noted in the domesticated counterparts of the species ana-
lyzed in the study. The standard karyotype for the domestic
pig is 19 pairs of chromosomes (2n = 38) and nucleolar orga-
nizer regions are localized, as in the wild boar, on the 8th
and 10th pair of chromosomes (Gustavsson, 1988).
