Analysis of secondary sex ratio in the fox (Vulpes vulpes L.)

Analysis of secondary sex ratio in the fox (Vulpes vulpes L.) Secondary sex ratio and its variability in relation to some paratypic and genetic factors were studied in the silver fox by analysis of data obtained at the Pushkinskii fur farm (Moscow oblast) in 1980–1989. A total of 17285 whelps were examined. The mean proportion of males over the ten years of observation was 0.536 ± 0.004. No effect of parent age or litter size on this proportion was found. Individual analysis of the progeny of a single parent revealed 44 males and 49 females showing significant deviations from the expected sex ratio (1 ♂: 1 ♀). These results can be used for reconstruction of pedigrees whose progeny yields regular deviations from the expected sex ratio. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Russian Journal of Genetics Springer Journals

Abstract

Secondary sex ratio and its variability in relation to some paratypic and genetic factors were studied in the silver fox by analysis of data obtained at the Pushkinskii fur farm (Moscow oblast) in 1980–1989. A total of 17285 whelps were examined. The mean proportion of males over the ten years of observation was 0.536 ± 0.004. No effect of parent age or litter size on this proportion was found. Individual analysis of the progeny of a single parent revealed 44 males and 49 females showing significant deviations from the expected sex ratio (1 ♂: 1 ♀). These results can be used for reconstruction of pedigrees whose progeny yields regular deviations from the expected sex ratio.
