Reciprocal effects for sexual maturity, egg production, egg quality traits and viability are well known in poultry crosses. They have been used in an optimal way to form profitable production hybrids. These effects have been hypothesized to originate from sex-linked genes, maternal effects or a combination of both. However, these may not be the only explanations for reciprocal effects. Recent mapping of quantitative trait loci (QTL) has revealed autosomal areas with parent-of-origin specific… 
Transcriptome-wide investigation of genomic imprinting in chicken
TLDR
The entire chicken genome was screened for parental-allele-specific differential expression on whole embryonic transcriptomes, using high-throughput sequencing and results come together, without a priori, with previous statements and phylogenetic considerations assessing the absence of genomic imprinting in chicken.
Incorporating parent-of-origin effects in whole-genome prediction of complex traits
TLDR
A whole-genome prediction model is built that incorporates parent-of-origin effects by considering parental allele substitution effects of single nucleotide polymorphisms and gametic relationships derived from a pedigree and it is indicated that, in order to gain benefit from the POE model in terms of prediction, a sizable contribution of parents' effects to variation is needed and such variation must be captured by the genetic markers fitted.
Detecting parent of origin and dominant QTL in a two-generation commercial poultry pedigree using variance component methodology
TLDR
Initial results suggest that variance component analysis can be applied within commercial populations for the direct detection of segregating dominant and parent of origin effects.
Next-Generation Sequencing Techniques Reveal that Genomic Imprinting Is Absent in Day-Old Gallus gallus domesticus Brains
TLDR
It is concluded that genomic imprinting is absent in the brains of 1-day-old chickens, due to the temporal and tissue specificity of imprinting, and the results cannot be extended to all growth stages and tissue types.
Comprehensive Review on the Existence of Genomic Imprinting in Aves
TLDR
A review of the evidence for and against imprinting in Aves found no transcript in the chicken transcriptome at incubation day 4.5 shows parentof-origin expression, providing strong evidence for a lack of imprinting at this stage of development.
A GWAS assessment of the contribution of genomic imprinting to the variation of body mass index in mice
TLDR
A brief review of a one-locus imprinting model in a quantitative genetics framework is given, and a decomposition of the genetic variance according to this model is provided, suggesting a non-negligible contribution of imprinting to genetic variation of complex traits.
Assessment of maternal and parent of origin effects in genetic variation of economic traits in Iranian native fowl
TLDR
Considering POE for BW8 and BW12 and maternal genetic effects for BW0 improved the accuracy of estimations and avoid reranking of birds for these traits.
Indirect Genetic Effects for Survival in Domestic Chickens (Gallus gallus) Are Magnified in Crossbred Genotypes and Show a Parent-of-Origin Effect
TLDR
Survival time was shorter in crossbreds than in purebreds, indicating outbreeding depression and the presence of nonadditive genetic effects, and absence of dominance variance in combination with considerable out breeding depression suggests that survival is affected by many loci.
Epigenetics and phenotypic variability: some interesting insights from birds
TLDR
The potential for epigenetic studies to improve the performance of individual animals through the implementation of limited changes in breeding conditions or the addition of new parameters in selection models is still an open question.
Identification of QTL for live weight and growth rate using DNA markers on chromosome 3 in an F2 population of Japanese quail
TLDR
The results indicated chromosome wide significant QTL for hatching weight, average daily gain from hatch to 1, 1–2 and 3–4 weeks of age and Kleiber ratio, an indirect criterion of feed efficiency, and dominance effect of QTL was significant.

Quantitative trait loci with parent-of-origin effects in chicken.
TLDR
It was shown that departure from fixation in the founder lines, grand-maternal effects, and Z-linked QTL were unlikely to give rise to any spurious parent-of-origin effects.
Genomic imprinting determines methylation of parental alleles in transgenic mice
TLDR
The methylation patterns of transgenic alleles were compared after transmission from mother or father in seven mouse strains carrying autosomal insertions of the same transgenic marker and showed a clear difference in DNA methylation specific for its parental origin, with the paternally inherited copy being relatively undermethylated.
What good is genomic imprinting: the function of parent-specific gene expression
TLDR
Three hypotheses claim to have found a countervailing selective advantage of parent-specific expression, proposed to have evolved because it enhances evolvability in a changing environment, protects females against the ravages of invasive trophoblast, or because natural selection acts differently on genes of maternal and paternal origin in interactions among kin.
The conflict theory of genomic imprinting: how much can be explained?

TLDR
The genetic conflict hypothesis is very successful in explaining the observed patterns of imprinting for autosomal genes and probably is the most likely evolutionary explanation for them, but for genes on X chromosomes, other processes of natural selection are more important.
Genomic imprinting and position-effect variegation in Drosophila melanogaster.
TLDR
It is shown that the imprint is due to the sex of the parent rather than to a conventional maternal effect, differential mitotic instability of the mini-X chromosome, or an allele-specific effect, which suggests that chromatin structure is important in maintenance of the imprint, but a separate mechanism may be responsible for its initiation.
Genome-wide scan for body composition in pigs reveals important role of imprinting.
TLDR
Testing for imprinting should become a standard procedure to unravel the genetic control of multifactorial traits, as it demonstrates the importance of knowing the homologies to human and mouse.
Allele-specific replication timing of imprinted gene regions
TLDR
Examination of replication timing patterns for the chromosomal regions containing the imprinted genes Igf2, Igf 2r, H19 and Snrpn in the mouse reveals that the two homologous alleles replicate asynchronously and it is always the paternal allele that is early-replicating.

A quantitative trait locus (QTL) analysis of growth and fatness data from a three generation pig experiment is presented, finding evidence for a large QTL affecting back fat and another for abdominal fat segregating on chromosome 4.
Parental legacy determines methylation and expression of an autosomal transgene: A molecular mechanism for parental imprinting
TLDR
A transgenic mouse strain is created in which an autosomal transgene bearing elements of the RSV LTR and a translocated c-myc gene obeys very unusual rules, providing direct molecular evidence that autosomal gene expression can depend upon the sex of the parent from which the gene is inherited.
Lessons from comparative analysis of species-specific imprinted genes

Comparison of a species-specific imprinted gene Impact using a broader range of mammals led us to propose an alternative dosage control hypothesis for the evolution of genomic imprinting.
