Condition and reproductive investment in the western mosquitofish (Gambusia affinis) : little evidence for condition-dependent sex-biased investment
In sexually reproducing species, resources may theoretically be distributed with bias to the production of male or female offspring in response to the condition of the mother, commonly recognized as sex allocation. Using a recently characterized sex-specific molecular marker, we tested for maternal sex allocation (i.e. maternal primary sex ratio bias and sex-specific offspring investment) in capti
