Chromosome variation in Peromyscus: a new mechanism.
Differences in total chromosome lengths between two karyotypically divergent groups of Peromyscus maniculatus are taken as evidence for an deletion mechanism of chromosomal variation in the species. The differences may be due in part to variation in the amount of constitutive heterochromatin in the two karyotypes.
