Chromosomal polymorphism and G-banding patterns in the wild boar (Sus scrofa L.) from the Netherlands

Genetica Aims and scope Submit manuscript

Cytogenetic examination of 15 wild pigs (Sus scrofa L.) from the Netherlands has revealed intrapopulation polymorphism for the diploid chromosome number. Eleven pigs showed 2n=36 chromosomes, three pigs showed 37 chromosomes, and one pig showed 38 chromosomes. The cause of these differences in chromosome number is discussed.

With the aid of a Giemsa banding technique it is demonstrated that the “extra” submetacentric chromosome (chromosome No. 1a) of the wild boar is homologous with chromosomes Nos. 15 and 17 of domestic pigs.
