Healthy males are likely to have higher mating success than unhealthy males because of differential expression of condition-
dependent traits such as mate searching intensity, fighting ability, display vigor, and some types of exaggerated morphological
characters. We therefore expect that most new mutations that are deleterious for overall fitness may also be deleterious for male
