When conspecific or closely related organisms are crossed, the ensuing hybridization can result in unique phenotypes known as transgressive traits, extreme in relation to those of the parents. Genetic models proposed so far cannot fully account for the formation of transgressive traits. Recent studies have identified transgressive expression of small RNA (sRNA) populations in hybrids of higher plants. The unique methods of inheritance of various sRNAs allows them to acquire novel targets in hybrids. To understand the inheritance of sRNAs in C.reinhardtii and their role in trangressive phenotype formation observed in recombinants, crossing experiments were designed. Data from these crosses has identified several transgressively expressed sRNAs. The resulting analysis will be linked to phenotypic screening of hybrids for transgressive traits.
