Abstract

Chromosome evolution in primitive Australian ants, collected from 56 localities in 1975-91, of the Myrmecia pilosula species complex was investigated in the context of the minimum interaction theory. Under the minimum interaction theory, selection favors rearrangements tending to reduce the...

Abstract

The C-banding patterns of 71 species of Hymenoptera were studied by chromosomal alteration network analysis and by karyograph analysis. Pseudoacrocentric chromosomes (AM) with extremely elongated heterochromatic arms, which were induced by saltatory growth of constitutive heterochromatin after...

Abstract

A karyograph method [see ABA 49, 3627] was applied to data on 1070 mammalian species. It was estimated that the chromosome number (n), chromosome arm number (AN) and karyonumber (n + AN) change at the rate of 1 per 5 300 000, 2 700 000 and 2 200 000 yr resp.

Abstract

The chromosomes of 21 species of Vespidae (consisting of 9 polistines and 12 vespines) were compared using an air-drying technique. The haploid number of Polistinae ranged broadly (n = 14-34), while it was either n = 25 or n = 26 in the Vespinae. There were no karyological similarities (in terms of ...
