We document significant variation in courtship ability, mating ability, sperm size and sperm production rate.
We implemented the PC analysis in JMP, including values for the following traits for each of the 7 strains (Table 2): courtship ability, mating ability, number of sperm transferred, spermatid size, sperm production rate, P2-early and P2-late.
Post-hoc tests (Hsu's MCB) showed that strains JU440, MY2 and PD4790 all had significantly higher mating success than the strain with poorest mating success (DR1350); strain DR1350 also exhibited the lowest courtship ability, with other strains having similar scores in our assay (Table 2, Figure 5).
Testing his courage and confidence for in person personal talk, commitment to the courtship, relationship mending ability, intellect, and loyalty to her sometimes allows the best man to get to her.
These traditions have largely broken down among the urban educated classes, where traditional and Western courtship styles have demonstrated the ability to intermingle.

It is rooted in the ability to engage in courtship, to cosset talent, to understand the human condition and to make decisions fast".
Subsequent to the evolution of ultrasonic hearing, the males of three Ostrinia species may have acquired the ability to produce quiet courtship ultrasounds that could be heard only by females in close proximity.
These isoforms display differences in their expression patterns and in their ability to rescue male courtship defects [ 22].
The loss of wing and tail feathers can affect a bird's ability to fly (sometimes dramatically) and in certain families can impair the ability to feed or perform courtship displays.
