چکیده
Institut National de La Recherche AgronomiqueStation de Recherches Avicoles, Domaine de l'Orfrasi&e, 37380 Nouzilly, France SUMMARY Selection could contribute to reduce sexual dimorphism of body weight and its negative consequences. Genetic differences between sexes at slaughter age were first studied. Heritabilities of male and female traits were different and genetic correlations between both traits significandy

Study of Sexual Dimorphism in Second-to-fourth Digit Length Ratio (2D: 4D) in the Green-Bellied Lizard (Darevskia cholorogaster) from Iran
Sexual dimorphism in digit ration is related to genetic differences between species in response to prenatal exposure to hormones. In this study, the development of tetrapod digits, preliminary the ratio between the length of digit II and IV (2D: 4D) was investigated in 34 samples of Darevskia cholorogaster in the North of Iran. The results showed no significant differences between sexes in any ...
متن کاملSexual 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...
متن کاملReduced Skull Sexual Dimorphism in a Local Sheep Breed
This study estimated the magnitude of sexual dimorphism in a relict sheep from Catalunya (NE Spain), called Fardasca,using geometric morphometric techniques. For these analyses, a total of 18 skull specimens (2 adult males and 16 females) were studied. Our results suggest that the breed is not cranially dimorphic, so sex determination using landmarks described here as criteria is likely to yiel...
متن کاملSexual dimorphism of Eastern mosquitofish (Gambusia holbrooki Girard, 1859) in Gamasiab River, Kermanshah province
Gambusia holbrooki Girard, 1859 is considered as one of the non-native and invasive species in the inland waters of Iran. This species occurs in most inland basins and aquatic bodies of Iran and has even been found in brackish waters. Extensive adaptations of this species to its different habitats caused numerous changes in its biological characteristics and morphological traits. The present st...

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 ...
