Positive genetic correlation between female preference and preferred male ornament in sticklebacks

Article Abstract:

The genetic correlation between male ornaments and female preference in Gasterosteus aculeatus was examined at the within population level. Using a full-sib/half-sib breeding design, wild-caught intense red and pale red males were crossed with 14 females representing the full range of preference phenoptypes. Results revealed a genetic variation in their daughters' preference for more intensely red males and in their sons' coloration. A positive correlation was also obtained for the redness of sons and the preference for red of daughters.

Condition-related mate choice in sticklebacks

Article Abstract:

Choice of mate by female laboratory-bred three-spined sticklebacks, Gasterosteus aculeatus, is well aligned with female physical condition. Linked with condition dependence of sexual traits, the covariance of mate preferences with condition could have repercussions for the evolution of preferences and preferred sexual characteristics. It must now be established whether mate preferences have condition-dependent expression.
