tendem duplication is the duplication process of the exon in which exon within the same gene gives rise to a subsequent exon. So in other words, 2 copies of the same exon are accumulated for one gene. This is a case in leukemia and is lethal. However, different duplications can give different results. Mostly, duplicated genes accumulate mutations faster than any other normal gene. The reversal of mutation in that duplicated gene can also occur spontaneously and at a high frequency. tendem duplication is the duplication process of the exon in which exon within the same gene gives rise to a subsequent exon.
