{"abstract":[{"lang":"eng","text":"The grasshopper Podisma pedestris contains two chromosomal races, which differ by a Robertsonian fusion between the sex chromosome and an autosome, and which meet in a narrow hybrid zone in the Alpes Maritimes. DNA content variation across this hybrid zone was investigated by optical densitometry of Feulgen stained spermatids. Spermatids from males with the unfused sex chromosome stain more strongly than those from males with the fused chromosome. The difference between the karyotypes is greater in the centre of the hybrid zone, suggesting that it is not a pleiotropic effect of the fusion itself, but is due instead to differences at closely linked loci."}],"oa":1,"oa_version":"Published Version","date_published":"1987-01-01T00:00:00Z","publist_id":"1733","type":"journal_article","publisher":"Nature Publishing Group","article_type":"original","page":"221 - 228","day":"01","intvolume":"        58","publication_identifier":{"issn":["0018-067X"],"eissn":["1365-2540"]},"language":[{"iso":"eng"}],"date_created":"2018-12-11T12:08:14Z","title":"Differences in DNA content between two chromosomal races of the grasshopper Podisma pedestris","article_processing_charge":"No","status":"public","acknowledgement":"s We would like to thank Manse East for technical assistance and M. et Mme Aviotti for their hospitality in France.
