WebSep 2, 2008 · A widely used indicator of phenotypic quality in evolutionary analyses is degree of symmetry (i.e., fluctuating asymmetry, FA) because it is a marker of developmental stability, which is defined as an organism's ability to develop toward an adaptive end-point despite perturbations during its ontogeny. WebFluctuating Asymmetry (FA) is the deviation from perfect bilateral symmetry in an organism. The more symmetrical an organism is, the better they are at handling developmental stress arising from environmental stress, genetic problems and developmental instability. [10]
WebMar 1, 2024 · Many studies have suggested that developmental instability (DI) could lead to asymmetric development, otherwise known as fluctuating asymmetry (FA). Several attempts to unravel the biological meaning of FA have been made, yet the main step in estimating FA is to remove the effects of directional asymmetry (DA), which is defined …
