To explore the potential of sex-linked polymorphisms for genetic parentage analyses in natural populations, we have employed a recently discovered X-linked autosomal loci) to deduce biological paternity and maternity for large numbers of encapsulated embryos within individual broods of the knobbed whelk ...
We further tested how sexual dimorphism and the mode of selection operating on the trait relate to the proportion of sex-linked genetic variance. Sexually selected traits did not show higher h2Z than morphological traits and there was only a weak positive relationship between h2Z and sexual ...
Genetic Heterogeneity Between the Three Components of the Autism Spectrum: A Twin Study This study investigated the etiology of autistic-like traits in the general population and the etiological overlap between the three aspects of the triad o... A Ronald,F Happé,P Bolton,... - 《Journal of...
Genetic and physical mapping of sex-linked AFLP markers in Nile tilapia (Oreochromis niloticus) Identification of the sex-determining genes of the Nile tilapia (Oreochromis niloticus) has important implications for commercial aquaculture. We previousl... L Bo-Young,C Jean-Pierre,OC Catherine,... ...
Homogamy, genetic similarity, and imprinting; parental influence on mate choice preferences Whereas the hypothesis of genetically mediated homogamy has been supported by several studies, certain theoretical and methodological criticisms have been ...

Investigations are currently being carried out to isolate a genetic marker linked to intersexuality using genetic map of the porcine genome. Such a marker will be useful in eradicating the mutation in pig breeding herds and in permiting the isolation of the gene responsible. 展开 关键词: Sex ...
Based on plumage traits it is impossible to reliably identify the sex of Water Rail and Spotted Crake In order to analyze their sexual size dimorphism we collected morphometric data and, for genetic control, feather pins as DNA source of 71 adult Water Rails and 31 Spotted Crakes during the ...
Fetal anatomic sex assignment is particularly useful in genetic counseling with regard to X-linked disorders and can be clinically important when either sex reversal, sex chromosome mosaicism, or ambiguous sex chromosomes are detected by prenatal diagnosis. Other features are also disclosed. 展开 ...
Problematic drug use was strongly linked with the `outdoor' (street or cruising ground) and `independent drifter' (from own phone or crack house) sex worker environments. 84% of those who were still working in these sectors reported current problem drug use, compared with just 13% of those...
