Changes in the additive variance of a fitness-related trait with inbreeding in Tribolium castaneum
In Tribolium castaneum, a fitness-related trait was defined as the total weight loss (TWL) of a vial after 21 days, due to the activity of a single pair of parents. TWL showed considerable inbreeding depression and strong heterosis. A significant increase in the heritability of TWL was observed with inbreeding. The results are compatible with the genetic variation of TWL in the base population being generated by segregation of a number of recessive alleles at low frequencies.
