The ability to identify genetic markers in nonmodel systems has allowed geneticists to
construct linkage maps for a diversity of species, and the sex-determining locus is often …

Arctic charr have a circumpolar distribution, persevere under extreme environmental
conditions, and reach ages unknown to most other salmonids. The Salvelinus genus is …

Abstract The South American acridid grasshopper Dichroplus pratensis (Melanoplinae) is
polymorphic and polytypic for a system of Robertsonian fusions across most of its …

We studied geographical body size variation in 23 populations and sexual size dimorphism
in 19 populations of the grasshopper Dichroplus pratensis Bruner in Argentina, spanning …

We report the results of a study on the neo-sex chromosome systems of six Neotropical
Melanoplinae species for contributing to a better understanding of their origin and behaviour …

Meiotic behaviour was studied in males of the Ctenomys perrensi superspecies from
Argentina that show variations in their chromosome number mostly due to Robertsonian …

This review focuses on grasshoppers that are polymorphic for Robertsonian translocations
be-cause in these organisms the clarity of meiotic figures allows the study of both chiasma …

Robertsonian changes account for many of the changes in the evolution of the orthopteran
karyotype; in their origin, a centric fusion is involved between two acro-telocentric …

The origin of neo-XY sex systems in Acrididae is usually explained through an X-autosome
centric fusion, and the behaviour of the neo-sex chromosomes has been solely studied in …

The history of the study of orthopteran chromosomes is coincident with the formulation of the
chromosome theory of heredity and the rediscovery of Mendel's laws, thus with the birth of …
