Maternal effects are now universally recognised as a form of nongenetic parental influence
on offspring but, until recently, paternal effects were regarded as an anomaly. Although it is …

Sexual reproduction is a fundamental aspect of life. It is defined by the occurrence of meiosis
and the fusion of two gametes of different sexes or mating types. Sex-determination …

Examples of genomic conflict were apparent soon after the inception of the field of modern
genetics. Despite these early discoveries, the relevance of genomic conflict to the core …

Environmental conditions experienced by parents are increasingly recognized to affect
offspring performance. We set out to investigate the effect of parental larval diet on offspring …

Background Although in all sexually reproducing organisms an individual has a mother and
a father, non-genetic inheritance has been predominantly studied in mothers. Paternal …

Sex chromosomes are typically viewed as having originated from a pair of autosomes, and
differentiated as the sex-limited chromosome (eg Y) has degenerated by losing most genes …

The evolution of aging requires mutations with late-life deleterious effects. Classic theories
assume these mutations either have neutral (mutation accumulation) or beneficial …

Exposing sires to various environmental manipulations has demonstrated that paternal
effects can be non-trivial also in species where male investment in offspring is almost …

Notwithstanding recent evidences, paternal environment is thought to be a potential but
unlikely source of fitness variation that can affect trait evolution. Here we studied …

Polyandry is widespread despite its costs. The sexually selected sperm hypotheses
('sexy'and 'good'sperm) posit that sperm competition plays a role in the evolution of …
