PATRI-paternity inference using genetic data
PATRI is a new application for paternity analysis using genetic data that accounts for the sampling fraction of potential fathers.
متن کاملExtra-Pair Paternity in Birds: Review of the Genetic Benefits
Question: How well are genetic benefits hypotheses for extra-pair paternity supported by empirical evidence? Data incorporated: Almost all published studies testing for genetic benefits from 1980 onwards (121 papers, 55 species). Analysis methods: Collected key features and findings of each study in a database. Determined overall level of support for both good genes and compatible genes hypothe...
متن کاملGenetic Patterns of Paternity and Testes Size in Mammals
BACKGROUND Testes size is used as a proxy of male intrasexual competition, with larger testes indicative of greater competition. It has been shown that in some taxa, social mating systems reflect variance in testes size, but results are not consistent, and instead it has been suggested that genetic patterns of mating may reflect testes size. However, there are different measures of genetic patt...
متن کاملGenetic dissimilarity predicts paternity in the smooth newt (Lissotriton vulgaris).
Under sperm competition, paternity is apportioned by polyandrous females according to the order of matings and the genetic quality of the inseminating males. In order to distinguish between these two effects, we sequentially paired 12 female smooth newts (Lissotriton vulgaris) with each of two males and, where possible, repeated the same procedure in reverse order of the identical males after a...
متن کاملThe degree of extra-pair paternity increases with genetic variability.
The amount of extra-pair paternity in socially monogamous bird species varies from 0% to 76% extra-pair offspring. The causes of this remarkable interspecific variation are largely unknown, although intraspecific analyses suggest that females seek extra-pair matings to improve the genetic quality of their offspring. If this is a general explanation for the occurrence of extra-pair matings, then...
