WebApr 1, 2013 · Cryptic genetic sequences have attenuated effects on phenotypes. In the classic view, relaxed selection allows cryptic genetic diversity to build up across individuals in a population, providing alleles that may later contribute to adaptation when co-opted— e.g., following a mutation increasing expression from a low, attenuated baseline. Webmutations in flies. Similarly, some of the genetic loci that affect the extent of transformation of teosinte toward maize-like structures are also of large effect (Figure 1). On the other hand, in Drosophila small effect mutations in Egfr can subtly modify the cryptic eye-roughening phenotype of a gain-of-function allele of the same gene.
