Future analyses concentrating on individual courtship components should be fruitful in dissecting the molecular bases of each of the courtship components.
Four of the seven courtship score QTL (CS1, CS3, CS6, and CS7) mapped closely to QTL for individual courtship components (see Figure 1 and Figure S4).
One can also distort a signal in unnatural but useful ways, as with testing the consequences of asynchrony between acoustic and visual courtship components when a living animal is incapable of such behavior.
Although each species share most aspects of courtship behaviours, they each differ in the timing, duration and frequency of different courtship components, making it an attractive model for studying the genetic basis of courtship evolution (Beukeboom and van den Assem, 2002; Beukeboom and van den Assem, 2001; van den Assem and Werren, 1994).
- Vibrations are an essential component of courtship and dominance contacts.
There are several key component of courtship, including sexual advances, mate choice, and receptivity.
Besides, in Arianta arbustorum dart shooting seems to be an optional component of courtship [ 10].
These families are noteworthy because they suggest a heritable component to courtship dysfunction.
Sound production is an important component of courtship displays in many animals, including insects, birds, and anurans (Searcy & Andersson, 1986).
However, courtship is an important component of sexual behaviour in some of the species considered and including this aspect of male behaviour may therefore change results.
