Summary

In colonies of bluegill, some males provide parental care for broods in nests, whereas other males steal fertilizations and do not provide parental care. Using experimental pond populations of bluegill of known genotype (determined through protein electrophoresis), we demonstrate that cuckolder males successfully fertilize eggs in parental male nests.

Methodology

Electrophoretic technique to assess fertilization, hand netted from Lake Opinicon
