Abstract:
Alternative methods of genetic evaluation which consider uncertain paternity were compared theoretically and through Monte Carlo simulation. Records were simulated for 300 base generation animals and 10 subsequent generations of 100 animals each. Probabilities of paternal uncertainty were either 20 or 50%, heritability was 0.05, 0.25 or 0.50, mating was random with a female-to-male ratio of 5, and selection of breeding animals was either random or by truncation on phenotype. Simulations were replicated 10 times. Differences in expected selection response, for the genetic evaluation methods studied, were largest when heritability was low and degree of paternal uncertainty high. Expected response to selection was maximized in all cases by using uncertain paternity methods instead of genetic grouping or other methods. Advantages over genetic grouping ranged from 0 to 16%. The exclusion of performance records of animals with paternal uncertainty reduced expected selection response by as much as 37%, in addition to the reduction in expected response caused by excluding from selection animals with uncertain parents. All methods that accounted for true or probable paternity, either directly or through genetic groups, yielded unbiased estimates of genetic trends. Key words: Uncertain parentage, numerator relationship matrix, genetic grouping, genetic evaluation, genetic progress, Monte Carlo Simulation

Abstract:
Paternal care, particularly in cases of uncertain paternity, carries significant costs. Extensive research, both theoretical and experimental, has explored the conditions in which paternal care behaviour would be favoured. Common explanations include an adjustment of care with uncertainty in paternity and limited accuracy in parentage assessment. Here, we propose a new explanation that microbes may play a role in the evolution of paternal care among their hosts. Using computational models, we demonstrate that microbes associated with increased paternal care could be favoured by natural selection. We find that microbe-induced paternal care could evolve under wider conditions than suggested by genetic models. Moreover, we show that microbe-induced paternal care is more likely to evolve when considering paternal care interactions that increase microbial transmission, such as feeding and grooming. Our results imply that factors affecting the composition of host microbiome may also alter paternal behaviour. This article is part of the theme issue ‘The role of the microbiome in host evolution’.

O sistema de acasalamento mais empregado na pecuária de corte extensiva é a monta a campo com o uso de reprodutores múltiplos. Este sistema traz diversas facilidades ao produtor, entretanto não permite a identificação da paternidade das crias, impossibilitando a comparação do desempenho reprodutivo e produtivo dos diferentes touros, o que afeta negativamente as avaliações genéticas e o progresso genético pela seleção. Objetivou-se com este trabalho comparar metodologias estatísticas que permitam considerar rotineiramente o uso da informação de acasalamentos com touros múltiplos na avaliação genética. Para tanto, foram analisados registros de ganhos de pesos pós-desmama e peso ao sobreano, mensurados em machos e fêmeas de animais da raça Nelore, nascidos no período de 1984 a 2006. Foram aplicados diferentes procedimentos estatísticos que consideram dados de animais com incerteza de paternidade na estimação de parâmetros e valores genéticos. As estimativas dos componentes de (co)variâncias genéticas e dos valores genéticos para os animais presentes no pedigree foram comparadas entre os diferentes procedimentos estatísticos. No capítulo 2, foram utilizados o modelo de paternidade desconhecida e o modelo de grupos genéticos para comparação. Verificou-se que o modelo de grupo genético, definido pelo intervalo de gerações dos machos deve ser usado para classificar e predizer o mérito genético dos filhos de reprodutores múltiplos. No capítulo 3, comparou-se o modelo com base na matriz de parentesco médio e o modelo hierárquico bayesiano (HIER) para incerteza de paternidade. Concluiu-se que o HIER é o modelo que melhor ajustou os dados para estimar os parâmetros genéticos de animais que possuem paternidade incerta. No capítulo 4, propôs-se uma aproximação do modelo hierárquico Bayesiano, usando procedimentos Bayesianos empíricos e máxima...
Multiple-sire (MS) mating is the most used mating system in extensive beef cattle systems. This system provides several conveniences to the farmers, but does not allow for paternity identification of the offspring, making impossible to compare the reproductive and productive performance of different bulls, negatively affecting the genetic evaluations and therefore the genetic progress. The aim of this work was to compare statistical approaches that allow for considering information from mating with multiple sires in genetic evaluation. Records from postweaning gain and long yearling weight, measured in males and females of Nellore animals, born from 1984 to 2006 were used. We applied different statistical approaches, which consider data from animals with uncertain paternity in the estimation of genetic parameters and values. The estimated values of the (co) variance components and breeding values for the animals in the pedigree were compared from the different statistical procedures. In chapter 2, we compared unknown parentage and genetic groups models. It was found that the genetic group model defined by the generation interval of males was more appropriate to predict the genetic merit of animals with unknown paternity. In chapter 3, we compared the model based on the use of an average numerator relationship matrix and a hierarchical Bayes model (HIER) accounting for uncertain paternity. We concluded that HIER was the best data fitting model to estimate genetic parameters of animals with uncertain paternity. In chapter 4, we proposed a Bayesian hierarchical model approximation, using empirical Bayesian procedures and maximum likelihood. The proposed model represented a computationally feasible alternative to calculate the probabilities of candidate sires and animal genetic effects on genetic evaluations of large datasets, when there are uncertainty paternity assignments for some animals

Abstract:
This article discusses the use of probabilistic reasoning to analyse a disputed paternity case, where the DNA genotypes are compatible on all markers but one, allowing for the possibility of mutation, when the mutation rate is itself uncertain. It first describes the construction and Bayesian analysis of a suitable model for paternity testing, taking into account the potentially misleading effect of genetic mutation and allowing for mutation rate uncertainty, before introducing the simplest type of disputed paternity case. It then considers a specific disputed paternity case, in which an apparent exclusion at a single marker could indicate either non-paternity or mutation, as well as the features of the mutation process that need to be accounted for in the analysis. The results of a simple analysis of the specific disputed paternity case are examined and the analysis is set in the broader context of DNA profiling and forensic genetics.

Abstract:
This chapter highlights common situations in perinatal counseling, including challenging circumstances, complex situations, and ethical dilemmas. It discusses conflicts that may arise from pregnancy termination; the complexities surrounding the identification of incidental findings such as misattributed paternity, discovery of consanguinity, or discovery of an incidental condition; and issues surrounding privacy and confidentiality, including familial implications of genetic knowledge. Also discussed are difficult circumstances such as couples in conflict or nonparticipation of a male partner and dealing with uncertainty in various situations including fetal diagnosis and prognosis, family history, complex conditions, and variants of uncertain significance. Conflicts around fetal sex determination and the disclosure of adult-onset conditions are discussed, as is the situation when a patient asks for provider guidance in making a decision. Barriers to the consenting process are discussed, as are the complexities of practicing in a field of rapidly evolving technologies.

Abstract:
Abstract.—The molecular ecology of many elasmobranchs, including dogfish, is still in its infancy, with phylogeographic, population genetic, and mating structure data restricted to a few species. Here, I describe the applications of molecular genetic methods, in sharks in general and in dogfish specifically, to issues ranging from broad-scale vertebrate phylogenies to taxonomic problems, identification of population structure and multiple paternity, and, as an outlook, genome-enabled investigations. New molecular data from dogfish are also presented. Sequence data suggest two distinct clades of dogfish in the North Pacific and Atlantic/South Pacific whose taxonomic position is uncertain but which represent independent evolutionary lineages. No genetic differentiation was detected in populations in the northeast Pacific, though the evolutionary dynamics of molecular markers indicate that ecologically independent populations may still exist. A recent collection of large amounts of sequence data from coding genes of dogfish provides exciting opportunities for future research, which should be carried out in close integration with ecological and environmental data.
