WebThese two assumptions lead inevitably to the capture of genetic variance into sexually selected traits concomitantly with the evolution of condition dependence. We present a simple genetic model to illustrate this view. We then explore some implications of genic capture for the coevolution of female preference and male traits. WebJan 7, 2010 · The genic capture hypothesis implies that the expression of sexual ornaments largely depends on genes affecting resource acquisition and use. The ornaments should thus show high degree of directional dominance typical of life-history traits, and consequently, they should be severely affected by inbreeding. Here we investigated the …
