Sex determination in ratite and non ratite birds by molecular method
The Indian Journal of Animal Sciences, 2016 In spite of number of methods for sex determination in birds, it is very difficult to distinguish sex especially in ratite birds due to lack of sexual dimorphism. Chromodomain helicase DNA binding 1 gene (CHD 1) is the choice of gene for gender differentiation using PCR based molecular method. In present study, non ratite CHD gene specific primers viz.

Journal of Anatomy, EarlyView.Sternum morphology varies among birds and is a function of body mass and order. The area of the sternum is inversely related to the area of the keel suggesting that the increase in bone mass associated with a large keel has been mitigated by a reduction in bone mass of the sternum.

Beyond the Chicken: Alternative Avian Models for Developmental Physiological Research
Frontiers in Physiology, 2021 Biomedical research focusing on physiological, morphological, behavioral, and other aspects of development has long depended upon the chicken (Gallus gallus domesticus) as a key animal model that is presumed to be typical of birds and generally ...

Austral Ecology, Volume 51, Issue 6, June 2026.ABSTRACT Presently, there are three main hypotheses to explain why the leaves of many Australian mistletoes resemble their hosts. The eco‐physiological convergence hypothesis suggests that mistletoes must manage their physiology, especially their water relations, to match those of the host, to avoid killing themselves or the host branch they have ...
