The management of misaligned paternity findings raises important controversy worldwide. It has mainly, however, been discussed in the context of high-income countries. Genetic and genomics research, with the potential to show misaligned paternity, are becoming increasingly common in Africa. During a genomics study in Kenya, a dilemma arose over testing and sharing information on paternal sickle...

The article represents an empirical study of paternity as a male personality development factor in men. Consensus is emerging that responsible fatherhood entitles the father to establish paternity, be present in the child's life, share economic support, and be personally involved in the child's life in collaboration with the mother. Literature reviews on fatherhood yield numerous empirical stud...

Prolactin has long been known to play a significant role in maternal care. When behavioral endocrinologists began to examine the endocrinology of fatherhood, prolactin was also found to be connected with paternal care in fish, birds, and mammals including primates.

We examine the demographic correlates of paternity confidence, or men's assessment of the likelihood that they are the genetic father of a particular child. Evolutionary theory predicts that men will provide less parental investment for putative genetic offspring who are unlikely to be their actual offspring, but confidence of paternity has not been as extensively examined as its importance wou...

The resolution of a paternity case is presented in which two indirect exclusions were found for the alleged father during routine paternity testing. Genetic studies on family members of the alleged father elucidated the inheritance pattern within the phosphoglucomutase (PGM1) and Duffy (Fy) blood group systems.

Minisatellite variant repeat (MVR) mapping using polymerase chain reaction (PCR) was applied to a practical case of paternity testing to evaluate the paternity probability. In order to obtain single allele mapping by allele-specific MVR-PCR, three flanking polymorphic sites for each of the MS31A and MS32 loci were investigated and all three individuals were typed as heterozygous for at least on...

BACKGROUND A large number of studies in postcopulatory sexual selection use paternity success as a proxy for fertilization success. However, selective mortality during embryonic development can lead to skews in paternity in situations of polyandry and sperm competition. Thus, when assessment of paternity fails to incorporate mortality skews during early ontogeny, this may interfere with correct...

By far the most contentious public policy issue in relation to DNA paternity testing is the status of those tests conducted without the knowledge or consent of the mother. Such tests are usually arranged by men, and involve comparison of samples from a man and his putative child. On this account they are often described as ‘motherless tests’, although not all motherless tests are done without t...

Paternity testing is being increasingly requested with the aim of challenging presumptive fatherhood. The ability to establish the biological father is usually based on the genotyping of autosomal short tandem repeat (STR) in alleged father, mother and child, but the use of Y-chromosomal STR has gained interest in the last few years. In this work, we propose a new probabilistic approach that co...

Identifying relationships between variables in ecological systems is challenging due to the large number of interacting factors. One system studied in detail is avian reproduction, where molecular analyses have revealed dramatic variation in rates of extra-pair paternity-the frequency with which broods contain individuals sired by different males. Despite the attention the topic has received, i...
