RésuméNous comparons les caryotypes polytènes de 7 espèces du genre Bilobella. L'analyse des séquences de We compare the polytene karyotypes of 7 species of the genus Bilobella. The analysis of the band sequences displays large interspecific differences, in contrast with the relative similarity of the external phenotypes. It is more particularly impossible to homologize all chromosomes through the seven species, and it is necessary to bring out eleven distinct types of chromosomes the combination of which leads to an haploid karyotype n = 7 in every species.The morphometric study of the karyotypes gives some results, but so far, only the characters of external morphology have allowed satisfying phylogenetic reconstruction of the genus. Such a situation is completely different from the one which is known in Diptera with polytene chromosomes, and states the problem of the genetic significance of the chromosomal band sequences in the chromosomes of Neanurinae Collenibola.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
