[ 1 ] - Sexual dimorphism in digit length ratios of the second to fourth digits (2D:4D) in two species of green toads (Pelobates syriacus Boettger, 1889 and Bufo viridis (Laurenti, 1768))
Sexual dimorphism in the ratio of digits length is a morphological feature resulted from the interaction between sex hormones and prenatal Hox genes, the latter is known to control the development of both limbs and genitals. The status of this trend and ratios have been investigated in various animal groups, including humans, other mammals, birds, reptiles, and amphibians. In this study, the bo...
[ 2 ] - Sexual dimorphism in digit length ratios of the second to fourth digits (2D:4D) in Blanford's fringe-toed lizard Acanthodactylus blanfordi Boulenger, 1918 (Sauria: Lacertidae) in the south of Iran
Finger length ratios are organized during embryonic development of fingers as they exposed to sex steroid hormones, and may show varying degrees of sexual dimorphism between males and females in different animal groups. Among all the finger length ratios calculated in a sample, the ratio between the second to fourth fingers (2D: 4D) is the most important one. In this study, the 2D:4D ratios in ...
[ 3 ] - Evaluation of sexual dimorphism on the basis of morphometric traits in Talysh toad, Bufo eichwaldi (Litvinchuk, Borkin, Skorinov & Rosanov, 2008), along with the evaluation of the conservation status of the species
The status of sexual dimorphism patterns in human and various animal groups including some mammals, birds, reptiles and amphibians have been studied, however, despite the fact that a growing number of studies were aimed to describe sexual dimorphism patterns in external morphological features such as the proportion of toes in animals, our knowledge of some basic issues, specially in some animal...
