Evolution and function of genomic imprinting in plants

WebGenomic imprinting in Drosophila is maintained by the products of Suppressor of variegation and trithorax group, but not Polycomb group, genes. Mol Genet Genomics … WebFeb 26, 2024 · Genomic imprinting is characteristic of two mammalian infraclasses, Metatherians (marsupials, such as possum and wallaby, which have an elemental placenta) and Eutherians (true placentals, such as humans and mice) [ 32 ]. In Monotremata (oviparous mammals such as the platypus and echidna) no imprinted genes were found [ … WebThe genetic systems of animals and plants are typically eumendelian. That is, an equal complement of autosomes is inherited from each of two parents, and at each locus, each parent's allele is equally likely to be expressed and equally likely to be transmitted. ...
