Web12. mar 2013 · A large number of SNPs (49) were located in the coding region, 33 representing synonymous and 16 non-synonymous changes. Most SNP-containing genes were related to immune response and gonad differentiation processes, and could be candidates for functional changes leading to phenotypic changes. Web31. máj 2024 · Epialleles are defined as ‘marked’ allelic forms whose phenotypic effects (if any) depend on their epigenetic states, rather than on DNA sequence differences. Type 2 involves changes associated with regulatory molecules such as small-interfering RNAs, which can be transmitted through the gametes, resulting in non-Mendelian inheritance.
