The butterfly Danaus chrysippus (L.) in East Africa comprises polyphyletic, sympatric lineages that are, despite behavioural isolation, driven to hybridization by female-biased sex ratios
Mitochondrial and nuclear DNA information was analysed among four subspecies of the African Queen butterfly, Danaus (Anosia) chrysippus sensu lato ( s.l. ), along with four other Danaus species drawn from all three subgenera ( D. ( Danaus ) plexippus , D. (Salatura) genutia , D. (A.) gilippus , D. ( A.) eresimus ) and two outgroup species from the same tribe, Tirumala septentrionis and Amauris ...
متن کاملheterogeneity within the orientalist discourse: representation of the orient in womens travelogues and mens paintings
from 1950s onward, new theories and critical approaches burgeoned across humanities. these theories were context-oriented; as a result, the analysis of discursive practices gained significance. thus, social, political, historical and cultural discourses that have been hitherto marginalized and considered inferior to literary texts, were introduced as important texts to be analyzed by critics. o...
A neo-W chromosome in a tropical butterfly links colour pattern, male-killing, and speciation
Sexually antagonistic selection can drive both the evolution of sex chromosomes and speciation itself. The tropical butterfly the African Queen, Danaus chrysippus, shows two such sexually antagonistic phenotypes, the first being sex-linked colour pattern, the second, susceptibility to a male-killing, maternally inherited mollicute, Spiroplasma ixodeti, which causes approximately 100% mortality ...
متن کاملA neo-sex chromosome in the Monarch butterfly, Danaus plexippus
We report the discovery of a neo-sex chromosome in Monarch butterfly, Danaus plexippus, and several of its close relatives. Z-linked scaffolds in the D. plexippus genome assembly were identified via sex-specific differences in Illumina sequencing coverage. Additionally, a majority of the D. plexippus genome assembly was assigned to chromosomes based on counts of 1-to-1 orthologs relative to the...
متن کاملHybrid queen butterflies from the cross Danaus chrysippus (L.) × D. gilippus (Cramer): confirmation of species status for the parents and further support for Haldane’s Rule
A cross between queen butterflies of the Palaeotropical species Danaus chrysippus and the Neotropical D.gilippus was achieved with difficulty in both directions. Only one progeny ( N = 70) was reared comprising sterile males and inviable females in a precisely 1:1 ratio. Both prezygotic and postzygotic barriers to gene flow are strong. The result supports Haldane’s Rule, to which we propose a m...
