Fifty-five men participating in a domestic violence treatment program agreed to complete a questionnaire and rate the degree to which their children looked like them. Ratings of paternal resemblance were positively correlated with the self-reported quality of the men's relationships with their children and inversely proportional to the severity of injuries suffered by their spouses. Analogous r...

Males exhibit striking variation in the degree to which they invest in offspring, from merely provisioning females with sperm, to providing exclusive post-zygotic care. Paternity assurance is often invoked to explain this variation: the greater a male's confidence of paternity, the more he should be willing to provide care. Here, we report a striking exception to expectations based on paternity...

Since the introduction in the mid-1980s of analyses of minisatellites for DNA analyses, a revolution has taken place in forensic genetics. The subsequent invention of the PCR made it possible to develop forensic genetics tools that allow both very informative routine investigations and still more and more advanced, special investigations in cases concerning crime, paternity, relationship, disas...

Matriliny has long been debated by anthropologists positing either its primitive or its puzzling nature. More recently, evolutionary anthropologists have attempted to recast matriliny as an adaptive solution to modern social and ecological environments, tying together much of what was known to be associated with matriliny. This paper briefly reviews the major anthropological currents in studies...

PATRI is a new application for paternity analysis using genetic data that accounts for the sampling fraction of potential fathers.

Males usually do not provide parental care and with good reason, they may be caring for the offspring of someone else. But there are cases of male-only care even when certainty of paternity is low: why? A new model suggests female choice may provide the answer.

Maternal grandmothers invest more in childcare than paternal grandmothers. This bias is large where the expression of preferences is unconstrained by residential and lineage norms, and is detectable even where marriage removes women from their natal families. We maintain that the standard evolutionary explanation, paternity uncertainty, is incomplete, and present an expanded model incorporating...

in the present study, genotyping of six short tandem repeat (str) loci including csf1po, d16s539, f13a01, f13b, lpl and hprtb was performed on genomic dna from 127 unrelated individuals from the iranian province of isfahan. the results indicated that the allele and genotype distributions were in accordance with hardy-weinberg expectations. the observed heterozygosity (ho), expected heterozygosi...
