Meiotic drive genes cause the degeneration of non-carrier sperm to bias transmission in
their favour. Males carrying meiotic drive are expected to suffer reduced fertility due to the …

Male X-linked meiotic drive systems, which cause the degeneration of Y-bearing sperm, are
common in the Diptera. Sperm killing is typically associated with fitness costs that arise from …

Selfish genetic elements that gain a transmission advantage through the destruction of
sperm have grave implications for drive male fertility. In the X-linked meiotic drive system …

A number of species are affected by Sex-Ratio (SR) meiotic drive, a selfish genetic element
located on the X-chromosome that causes dysfunction of Y-bearing sperm. SR is transmitted …

The sex ratio (SR) X-linked meiotic drive system in stalk-eyed flies destroys Y-bearing
sperm. Unlike other SR systems, drive males do not suffer fertility loss. They have greatly …

Meiotic drive results when sperm carrying a driving chromosome preferentially survive
development. Meiotic drive should therefore influence sperm competition because drive …

The phenotype‐linked fertility hypothesis proposes that male fertility is advertised via
phenotypic signals, explaining female preference for highly sexually ornamented males. An …

Sexually selected ornaments are highly variable and the factors that drive variation in
ornament expression are not always clear. Rare instances of female-specific ornament …

Highlights•We studied sperm allocation in tephritid flies with contrasting life histories and
multiple sperm storage organs.•Sperm storage varied according to oviposition …

Sperm competition is common in many insect species; however, the mechanisms underlying
differences in sperm precedence are not well understood. In the stalk‐eyed fly, Cyrtodiopsis …
