Defining <strong>Symmetry</strong>/Asymmetry<br />
• <strong>Symmetry</strong><br />
– Based upon traits <strong>that</strong> are, on average, bilaterally symmetrical<br />
• Fluctuating Asymmetry (FA)<br />
– An average <strong>of</strong> any symmetrical deviation<br />
– Low FA = “Good”<br />
– High FA = “Bad”<br />
Key Reference: A study across 42 different species<br />
- On average, low FA individuals mate more<br />
- Low FA individuals found more attractive
