▪ Abstract Insect molecular systematics has undergone remarkable recent growth. Advances
in methods of data generation and analysis have led to the accumulation of large amounts of …

The genomes of multicellular eukaryotes provide information that determines the phenotype.
However, not all sequences in the genome are required for this purpose. Other sequences …

Here we report the genome sequence of the honeybee Apis mellifera, a key model for social
behaviour and essential to global ecology through pollination. Compared with other …

Recent decades have witnessed an explosion of theoretical and empirical studies of sex
allocation, transforming how we understand the allocation of resources to male and female …

Here we report the genome sequence of the honeybee Apis mellifera, a key model for social
behaviour and essential to global ecology through pollination. Compared with other …

Retroviruses and LTR retrotransposons comprise two long-terminal repeats (LTRs)
bounding a central domain that encodes the products needed for reverse transcription …

Rex1, together with the related Babar elements, represents a new family of non-long-
terminal-repeat (non-LTR) retrotransposons from fish, which might be related to the CR1 …

Retroviruses are often expressed in the placenta. Placental expression probably evolved to
facilitate retroviral transmission from mother to offspring and from offspring to mother. In the …

We ask whether the observed mitochondrial DNA (mtDNA) population subdivision of
Drosophila simulans is indicative of organismal structure or of specific processes acting on …

Little is known about the origin and evolution of supernumerary (B) chromosomes. This
study utilizes molecular markers to examine the evolutionary history and microstructural …
