Therefore, interactions between DNA and RNA provide a simple mechanism of genetic self-detection within nuclei. Imprinted RNAs could enable alleles of maternal and paternal origin to detect whether they are the same (homozygous) or different (heterozygous), and thereby provide strategic information about expected relatedness to siblings.en-USinclusive fitnessimprintingsiRNAgreen beardsrelatednessImprinted green beards: a little less than kin and more than kindJournal Article2015-10-08David Haig2015-12-1510.1098/rsbl.2013.0199
