Description
6 AprilExam 3April 15Genomic ImprintingFor a few mammalian traits the phenotype depends on which parent passed along the allele for those traitsSuch variation in phenotype is called genomic imprintingGenomic imprinting involves the silencing of certain genes that are stamped with an imprint during gamete productionIt appears that imprinting is the result of the methylation addition of CH of DNA3Genomic imprinting is thought to affect only a small fraction of mammalian genesMost imprinted genes are critical for embryonic developmentInheritance of Organelle GenesExtranuclear genes or cytoplasmic genes are genes found in organelles in the cytoplasmMitochondria chloroplasts and other plant plastids carry small circula
