This may explain why glucose-growing cells show superior mating efficiency compared to cells grown on respiratory carbon sources.
Third, higher flight performance may assist in achieving benefits associated with earliness, such as superior mates and resources (Husak and Fox 2008).
All these mating schemes have shown some benefits in increased genetic gain and/or reduced inbreeding but comparisons reported in the literature have not concluded on any clearly superior mating design, partly because only a limited number of mating designs were considered in each of the comparisons.
Whichever explanation applies to N. californicus, owing to their hyperaggressive behaviour small males were the superior interference mate competitors, reducing the likelihood of encounter between the females and the standard-sized males and thereby counterbalancing the female preference for standard-sized males.
Grading usually refers to the mating of average, or "grade," females to a superior male, then backcrossing the female offspring to the same or a similar sire.
To explain this, biologists have theorised that these females are mating with males who are genetically superior to their regular mates, thus getting the benefit of parental assistance from a cuckold and good genes from a Lothario.Proving that, though, is a lengthy process.
However, our presentation of three males to each mated female makes it likely that at least one male would be superior to her original mate.
