Differences between males and females in the optimal phenotype that is favoured by
selection can be resolved by the evolution of differential gene expression in the two sexes …

Intralocus sexual conflict occurs when selection on a shared trait in one sex displaces the
other sex from its phenotypic optimum. It arises because many shared traits have a common …

A number of genes associated with sexual traits and reproduction evolve at the sequence
level faster than the majority of genes coding for non-sex-related traits. Whole genome …

In addition to delivering a haploid genome to the egg, sperm have additional critical
functions, including egg activation, origination of the zygote centrosome and delivery of …

Given their copy number differences and unique modes of inheritance, the evolved gene
content and expression of sex chromosomes is unusual. In many organisms the X and Y …

Spermatogenesis is a long and complex process that, despite the shared overall goal of
producing the male gamete, displays striking amounts of interspecific diversity. In this …

Studies of morphology, interspecific hybridization, protein/DNA sequences, and levels of
gene expression have suggested that sex-related characters (particularly those involved in …

The evolution of heteromorphic sex chromosomes (eg, XY in males or ZW in females) has
repeatedly elicited the evolution of two kinds of chromosome-specific regulation: dosage …

CRISPR gene drives have potential for widespread and cost-efficient pest control, but are
highly controversial. We examined a potential gene drive targeting spermatogenesis to …

Genes with male-and testis-enriched expression are under-represented on the Drosophila
melanogaster X chromosome. There is also an excess of retrotransposed genes, many of …
