Web23 Feb 2024 · The imprinting factor (IF) is a measure of the degree to which the gene is biased in favor of one parent in both directions of the reciprocal cross (Fig. 4 ). Briefly, the IF is a conservative estimate of the degree to which the A allele is more highly expressed when inherited from the favored parent compared to the less-favored parent (Fig. 4 ). WebInterestingly, most imprinted genes are found in clusters [1,14]. These clusters usually feature a complex balance of both maternally- and paternally-imprinted genes in the same (often megabase-sized) locus, and many of the clusters are regulated by (and regulate) the transcriptional activity of a long noncoding RNA (lncRNA) [12]. chrysothrixWeb26 Mar 2024 · Imprinted Genes Are Preferentially Affected by Positive Selection.
