Does multiple paternity influence offspring disease resistance?
It has been suggested that polyandry allows females to increase offspring genetic diversity and reduce the prevalence and susceptibility of their offspring to infectious diseases. We tested this hypothesis in wild-derived house mice (Mus musculus) by experimentally infecting the offspring from 15 single- and 15 multiple-sired litters with two different strains of a mouse pathogen (Salmonella Ty...
متن کاملMultiple paternity does not depend on male genetic diversity
Polyandry is common in many species and it has been suggested that females engage in multiple mating to increase the genetic diversity of their offspring (genetic diversity hypothesis). Multiple paternity occurs in 30% of litters in wild populations of house mice, Mus musculus musculus, and multiple-sired litters are genetically more diverse than single-sired ones. Here, we aimed to test whethe...
متن کاملFemale influence over offspring paternity in the red flour beetle Tribolium castaneum.
In animals having internal fertilization, both sexes can potentially influence the post-copulatory processes of sperm transfer, sperm storage and sperm use for fertilization. In this experiment, we investigated whether Tribolium castaneum females can influence male paternity success following consecutive matings with two different males. We compared second male paternity success (P2) between fe...
متن کاملMultiple paternity and genomic imprinting.
IN its simplest form, the genetic-conflict hypothesis players are alleles at a locus, strategies are the alleles’ patterns of expression, and an unbeatable (Hamilton for the evolution of genomic imprinting posits that multiple paternity of a female’s offspring, in combina1967) or evolutionarily stable strategy (Maynard Smith and Price 1973) is a pattern of expression, which, when tion with post...

Introduction: Acne is a common problem in adolescent and youngage groups, for which several risk factors have been suggested.One of the risk factors is smoking. In studies on the relationshipbetween smoking and acne, conflicting results have been obtained.Method: This study was conducted on 133 male patients whowere visited at the dermatology clinic of Imam Reza hospital dueto acne as the case ...
