Ectrodactyly in sisters and half sisters.
An extended family is described in which four sisters and half sisters presented with ectrodactyly. Two of the sisters had associated agenesis of the tibiae. The paper describes the malformations and discusses the management and possible genetic inheritance involved. An autosomal recessive gene seems likely to be the mode of inheritance.
متن کاملWild female baboons bias their social behaviour towards paternal half-sisters.
Adult female cercopithecines have long been known to bias their social behaviour towards close maternal kin. However, much less is understood about the behaviour of paternal kin, especially in wild populations. Here, we show that wild adult female baboons bias their affiliative behaviour towards their adult paternal half-sisters in the same manner and to the same extent that they bias their beh...
متن کاملFemale rhesus macaques discriminate unfamiliar paternal sisters in playback experiments: support for acoustic phenotype matching.
Widespread evidence exists that when relatives live together, kinship plays a central role in shaping the evolution of social behaviour. Previous studies showed that female rhesus macaques (Macaca mulatta) recognize familiar maternal kin using vocal cues. Recognizing paternal kin might, however, be more difficult as rhesus females mate promiscuously during the possible conception period, most p...
متن کاملKin recognition by paternal half-siblings in captive Papio cynocephalus.
Our objective in this study was to evaluate whether a group of paternally related, subadult baboons (Papio cynocephalus) would preferentially interact with kin or nonkin when they had been raised apart from kin other than their mothers. Subjects and their mothers were removed from the breeding group and placed in alternate housing within 24 h after birth to ensure that the subjects would not ha...
متن کاملThe Type I Generalized Half Logistic Distribution
In this paper, we considered the half logistic model and derived a probability density function that generalized it. The cumulative distribution function, the $n^{th}$ moment, the median, the mode and the 100$k$-percentage points of the generalized distribution were established. Estimation of the parameters of the distribution through maximum likelihood method was accomplished with the aid of c...
