A Chip off the Old Block: A Model for the Evolution of Genomic Imprinting via Selection for Parental Similarity

From: Genetics | Date: October 1, 2006| Author: Clark, Andrew G; Spencer, Hamish G | Copyright information

ABSTRACT

A consequence of genomic imprinting is that offspring are more similar to one parent than to the other, depending on which parent's genes are inactivated in those offspring. We hypothesize that genomic imprinting may have evolved at some loci because of selection to be similar to the parent of one sex or the other. We construct and analyze an evolutionary-genetic model of a two-locus two-deme system, in which one locus codes for a character under local selection and the second...

A genetic gender gap. (genomic imprinting)
Science News ; A Genetic Gender Gap Every high-school biology student knows the story: In a small monastery garden in the 1850s, Gregor Mendel tallied the offspring of smooth and wrinkled peas, giving birth to the modern science of genetics. The monk-scientist observed that pea progeny inherit the traits of both
Imprinting Capacity of Gamete Lineages in Caenorhabditis elegans
Genetics ; ... localized nature of the desilencing response is supported by genetic mapping, from which uniform GFP expression in each line maps solely to the integrated array. No evidence for second site-activating mutations was obtained in outcross experiments. Southern ...
Population Models of Genomic Imprinting. II. Maternal and Fertility Selection
Genetics ; ABSTRACT Under several hypotheses for the evolutionary origin of imprinting, genes with maternal and reproductive effects are more likely to be imprinted. We thus investigate the effect of genomic imprinting in single-locus diallelic models of maternal and fertility selection. First, the model
Sex-Specific Viability, Sex Linkage and Dominance in Genomic Imprinting
Genetics ; ABSTRACT Genomic imprinting is a phenomenon by which the expression of an allele at a locus depends on the parent of origin. Two different two-locus evolutionary models are presented in which a second locus modifies the imprinting status of the primary locus, which is under differential selection
Parent-of-Origin Effects on mRNA Expression in Drosophila melanogaster Not Caused by Genomic Imprinting
Genetics ; ABSTRACT Parent-of-origin effects create differences in gene expression among genetically identical individuals. Using measurements of allele-specific expression, we demonstrate that previously reported parent-of-origin effects on standing mRNA levels in Drosophila melanogaster are not attributable
Kin Recognition in Aleochara bilineata Could Support the Kinship Theory of Genomic Imprinting
Genetics ; ABSTRACT Genomic imprinting corresponds to the differential expression of a gene according to its paternal or maternal origin. The kinship theory of genomic imprinting proposes that maternally or paternally inherited genes may be in conflict over their effects on kin differently related along the
Maternal Effects as the Cause of Parent-of-Origin Effects That Mimic Genomic Imprinting
Genetics ; ABSTRACT Epigenetic effects are increasingly recognized as an important source of variation in complex traits and have emerged as the focus of a rapidly expanding area of research. Principle among these effects is genomic imprinting, which has generally been examined in analyses of complex traits
A Differential Dosage Hypothesis for Parental Effects in Seed Development
Plant Cell ; Parent-of-origin effects generate phenotypes that depend on the direction of a cross. This phenomenon occurs frequently during angiosperm seed development, where maternal influence is most common (Alleman and Doctor, 2000). Various genetic mechanisms can contribute to parentof-origin effects during
