In order to examine gene expression in the pupal wing tissue of Bicyclus anynana, we present an optimized protocol for in situ hybridizations using riboprobes. We also provide guidelines for the further optimization of this protocol for use in pupal wings of other Lepidopteran species.

Source: David Guo, College of Engineering, Technology, and Aeronautics (CETA), Southern New Hampshire University (SNHU), Manchester, New Hampshire An airfoil is a 2-dimensional wing section that represents critical wing performance characteristics. The pressure distribution and lift coefficient are important parameters that characterize the behavior of airfoils. The pressure distribution is directly related to the lift generated by airfoils. A Clark Y-14 airfoil, which is used in this...

Source: David Guo, College of Engineering, Technology, and Aeronautics (CETA), Southern New Hampshire University (SNHU), Manchester, New Hampshire A wing is the major lift-generating apparatus in an airplane. Wing performance can be further enhanced by deploying high-lift devices, such as flaps (at the trailing edge) and slats (at the leading edge) during takeoff or landing. In this experiment, a wind tunnel is utilized to generate certain airspeeds, and a Clark Y-14 wing with a flap and slat...

Source: Jose Roberto Moreto, Gustaaf Jacobs and Xiaofeng Liu, Department of Aerospace Engineering, San Diego State University, San Diego, California The delta wing, shown in Figure 1D, is a popular design in high-speed airplanes due to its superb performance in transonic and supersonic flight regimes. This type of wing has a small aspect ratio and high sweep angle, which reduces drag at high subsonic, transonic and supersonic flight regimes. The aspect ratio is defined as the wing span divided...

This work presents a simple and visual method to detect multi-nucleotide polymorphisms on a pneumatic droplet manipulation platform. With the proposed method, the entire experiment, including droplet manipulation and detection of multi-nucleotide polymorphisms, can be performed near 23 °C without the aid of advanced instruments.
FAQs
Genetic variation does not act in isolation. Genetic differences can interact with developmental pathways, while conditions experienced during early growth influence how those traits are expressed. This interaction helps explain why members of one species can develop different wing forms and why the resulting phenotypes may differ in flight capacity, dispersal, or reproductive investment.
Crowding, nutrition, and season function as environmental cues during early growth. Their importance is not simply that they change development generally; they can alter the expression of wing-development traits in individuals with relevant genetic variation. Examining these conditions therefore helps separate inherited influences from environmentally responsive expression when explaining wing polymorphism.
The forms can be compared through their associated life-history consequences. Differences in flight capacity relate to movement, differences in dispersal relate to spread through populations, and differences in reproductive investment relate to allocation of resources. Considering all three outcomes prevents researchers from treating wing shape alone as the complete phenotype and connects wing polymorphism to broader evolutionary questions.
Wing polymorphism provides a genetics example of a complex phenotype because its expression reflects both genetic variation and environmental conditions. This differs from an interpretation based only on genes or only on surroundings. The combined view is useful for studying how developmental pathways translate inherited variation and early-life cues into alternative forms within a species.
A basic investigation begins by identifying distinct wing forms within a species and recording associated differences in flight capacity, dispersal, or reproductive investment. Researchers then examine genetic variation, developmental pathways, and early-growth conditions such as crowding, nutrition, or season. Relating these factors to observed forms reveals how inherited and environmental influences jointly shape the phenotype.
The research approach is especially informative when the question concerns adaptation or population dynamics. Comparing wing forms can show how variation in movement, dispersal, and reproductive investment may contribute to how populations persist or change. It also provides a way to examine the spread of insects, making the topic relevant to evolutionary biology and pest-management research.
In genetics, the key outcome is not merely cataloging alternative wings. The broader result is insight into gene-environment interaction in complex phenotypes and life-history strategies. Wing polymorphism can therefore serve as a model for connecting inherited variation with developmental expression, ecological conditions, and consequences for adaptation, population dynamics, and insect spread.
