A model for genomic imprinting in the social brain: juveniles.
What are imprinted genes doing in the adult brain? Genomic imprinting is when a gene's expression depends upon parent of origin. According to the prevailing view, the "kinship theory" of genomic imprinting, this effect is driven by evolutionary conflicts between genes inherited via sperm versus egg. This theory emphasizes conflicts over the allocation of maternal resources, and focuses upon gen...
متن کاملA model for genomic imprinting in the social brain: elders.
Genomic imprinting refers to the process whereby genes are silenced when inherited via sperm or egg. The most widely accepted theory for the evolution of genomic imprinting-the kinship theory-argues that conflict between maternally inherited and paternally inherited genes over phenotypes with asymmetric effects on matrilineal and patrilineal kin results in self-imposed silencing of one of the c...
متن کاملA model for genomic imprinting in the social brain: adults.
Genomic imprinting refers to genes that are silenced when inherited via sperm or via egg. The silencing of genes conditional upon their parental origin requires an evolutionary explanation. The most widely accepted theory for the evolution of genomic imprinting-the kinship theory-argues that conflict between maternally inherited and paternally inherited genes over phenotypes with asymmetric eff...
متن کاملGenomic imprinting, maternal care, and brain evolution.
The majority of autosomal genes are inherited as two copies, one from each parent, and such biallelically inherited genes have identical functions. Genomic imprinting confers different functions on the two parental genomes during development by silencing one allele of each imprinted gene in a parent-oforigin-dependent manner. Hence imprinted genes usually function when inherited either from the...
متن کاملThe influence of genomic imprinting on brain development and behavior
Genomic imprinting, a newly discovered and significant form of gene regulation, refers to the differential expression of a gene depending on whether it is inherited from the male or female parent. The genetic conflict theory of genomic imprinting postulates that conflicts between the genetic interests of mothers, fathers, and their offspring, as well as asymmetric genetic relationships with mat...
