Directional asymmetry in gonad length indicates moray eels (Teleostei, Anguilliformes, Muraenidae) are “right-gonadal” [PDF]
Scientific Reports, 2023 Directional asymmetry indicates a unidirectional deviation from perfect bilateral symmetry, which was rarely examined in the inner organs of the teleost (Teleostei) compared to external traits.

Attempting genetic inference from directional asymmetry during convergent hindlimb reduction in squamates [PDF]
Ecology and Evolution, 2022 Loss and reduction in paired appendages are common in vertebrate evolution. How often does such convergent evolution depend on similar developmental and genetic pathways?

Shape Directional Asymmetry in Hindlimb Pairs among Calves (Bos Taurus) [PDF]
Animals, 2022 The aim of this study was to determine paired asymmetries (right–left) in the autopods of bovine hindlimbs using geometric morphometry (GM). A total of 28 hindlimb right–left matched autopods belonging to healthy Brown Pyrenean calves were assessed ...

Comparative Fluctuating Asymmetry and Directional Asymmetry in Four Cattle Skulls [PDF]
Veterinary Medicine and ScienceThis study investigates fluctuating asymmetry (FA) and directional asymmetry (DA) in the skulls of four cattle breeds: Eastern Anatolian Red, Southern Anatolian Red, Holstein and Simmental by using geometric morphometrics methods.

Shape, Size and Bilateral Asymmetry of the Humerus and Femur in the Common Swift (Apus apus) [PDF]
AnimalsCommon swifts are extreme aerial specialists that spend most of their lives in flight and use their legs mainly for clinging rather than locomotion. Because functional load is therefore expected to be concentrated on the wing, we hypothesized that the ...

A conserved teleost motor asymmetry requires evolutionary retention of vision [PDF]
iScienceSummary: Behavioral laterality is a prominent Bilateria feature, where motor functions are performed with a directional preference. Underlying such behaviors is thought to be hemispheric specializations that improve behavioral performance.

Spatial Variability of Small-leaved Linden (Tilia cordata Mill.) Leaf Blade [PDF]
E3S Web of Conferences, 2021 The features of asymmetry and shape of small-leaved linden leaf blades (Tilia cordata Mill.) on the Kola Peninsula (Murmansk region, Kirovsk) and in the middle part of Russia (Moscow region, Orekhovo-Zuevo) were studied.

About the asymmetry structure of the leaf blade Common plantain [PDF]
E3S Web of Conferences, 2021 Using the method of geometric morphometrics the contour of the image of the leaf blade of the Common plantain (Plantago major) was aligned along the axis of symmetry to answer the question of whether the asymmetry and shape were influenced by ...

Scutation asymmetries in red-footed tortoise Chelonoidis carbonaria Spix, 1824 (Testudines: Testudinidae) [PDF]
Papéis Avulsos de Zoologia, 2020 The ability of an individual to withstand random perturbations during its development is considered a good indicator of environmental and genetic stress. A common means of assessing developmental stability is through analysis of fluctuating asymmetry (FA)
