Sexually concordant selection occurs when selection favors the same alleles in both sexes but differs in relative strength between them. Thus sex-limited epigenetic traits may have played a pivotal role in the evolution of mammals and other species, particularly as a mechanism to ameliorate intralocus conflict between the sexes.
Large-scale association analysis identifies 13 new susceptibility loci for coronary artery disease.
Featured Content. The inheritance and presentation of all three differ depending on the sex of both the parent and the child. While the examples above certainly contain aspects of animal behavior, a more overt example of it in relation to sex-limited traits is detailed in a Teplitsky et al. Add links.
Parsch and Ellegren also assert that "sex-biased genes expressed only in sex-limited reproductive tissues evolve faster than unbiased genes that are expressed only in a single, non-reproductive tissue.
Genetic effects of each sex should also be estimated for transient traits such as RNA and protein levels. Removing technical variability in RNA-seq data using conditional quantile normalization. Also, few appropriate analytical methods have been employed to explain sex-influenced traits. Full size image.
This was aimed at preventing an influence of unequal sample numbers on results. Asymptotic conditional singular value decomposition for high-dimensional genomic data. Table 1 Analytical models for estimating sex-specific genetic effects on complex traits.
Dietmar Lippold for his suggestions regarding data analysis and preparation of this manuscript. Garver W. An example of sex-limited genes are genes which control horn development in sheep  : while both males and females possess the same genes controlling horn development, they are only expressed in males.
