Sex allocation theory for simultaneous hermaphrodites has focused primarily on the effects of sperm competition, but the role of mate choice has so far been neglected. We present a model to study the coevolution of cryptic female choice and sex allocation in simultaneous hermaphrodites. We show that the mechanism of cryptic female choice has a strong effect on the evolutionary outcome: if indiv...

to reproductively interfere between them (Pigot and Tobias 2013). Results for a series of cryptic butterfly species revealed only restricted contact zones on mainland and chequered distributions over narrow (3–10 km) sea straits (Dincă et al. 2011, Dapporto et al. 2012, Sañudo-Restrepo et al. 2013). If chequered distributions are overrepresented among cryptic species, they could encompass a dis...

Amphibians constitute a diverse yet still incompletely characterized clade of vertebrates, in which new species are still being discovered and described at a high rate. Amphibians are also increasingly endangered, due in part to disease-driven threats of extinctions. As an emergency response, conservationists have begun ex situ assurance colonies for priority species. The abundance of cryptic a...

Mutations in the splicing factor SF3B1 are found in several cancer types and have been associated with various splicing defects. Using transcriptome sequencing data from chronic lymphocytic leukemia, breast cancer and uveal melanoma tumor samples, we show that hundreds of cryptic 3' splice sites (3'SSs) are used in cancers with SF3B1 mutations. We define the necessary sequence context for the o...

Disruption of certain genes can reveal cryptic genetic variants that do not typically show phenotypic effects. Because this phenomenon, which is referred to as 'phenotypic capacitance', is a potential source of trait variation and disease risk, it is important to understand how it arises at the genetic and molecular levels. Here, we use a cryptic colony morphology trait that segregates in a yea...

We have investigated the possible role of a conserved cis-acting element, the cryptic AUG, present in the 5' UTR of coxsackievirus B3 (CVB3 ) RNA. CVB3 5' UTR contains multiple AUG codons upstream of the initiator AUG, which are not used for the initiation of translation. The 48S ribosomal assembly takes place upstream of the cryptic AUG. We show here that mutation in the cryptic AUG results in...

T H E insertion of h into the chromosome of Escherichia coli K12 increases the distance between the loci gal and bio, bracketing the prophage. Thus the frequency of PI mediated joint transduction of gal and bio from a lysogenic donor is considerably lower than that from a non-lysogenic one (ROTHMAN 1965). Accordingly, the frequency of gal-bio cotransduction from a donor carrying a deletion in i...
