Abstract We show that the degree of Gauss maps on abelian varieties is semicontinuous in families, and we study its jump loci. As an application obtain case theta divisors this answers Schottky problem. Our proof computes by specialization Lagrangian cycles cotangent bundle. also get similar results for intersection cohomology with a finite morphism to variety; it follows many components Andreo...

MOTIVATION Increasing evidences suggest that most of the genome is transcribed into RNAs, but many of them are not translated into proteins. All those RNAs that do not become proteins are called 'non-coding RNAs (ncRNAs)', which outnumbers protein-coding genes. Interestingly, these ncRNAs are shown to be more tissue specifically expressed than protein-coding genes. Given that tissue-specific ex...

The objective of this study was to identify the quantitative trait loci (QTL) affecting carcass traits on chromosome 1 in Japanese quail. The populations comprised of 422 progeny in 9 half-sib families. Phenotypic data on carcass weight, carcass parts, and the internal organs were collected on 422 progeny. Nine half-sib families were genotyped for 8 microsatellite markers covering chromosomes 1...

this study aimed to investigate the contribution of four common dfnb (“dfn” for deafness and “b” for autosomal resessive locus) loci and gjb2 gene mutations (exon 2) in hearing impairment in individuals living in markazi and qom provinces of iran. forty consanguineous iranian families with at least three affected individuals in family or pedigree who suffer from an autosomal recessive non-syndr...

Exploring elite alleles based on association analysis of economic traits will promote the breeding, development, and utilization Prunus sibirica resources. This study used 113 P. clones with diverse provenances to perform mapping 20 149 pairs highly polymorphic simple sequence repeat (SSR) markers. Population structure split into three subgroups. General linear model (GLM) mixed (MLM) identifie...

Splitting type loci are the natural generalizations of Brill-Noether varieties for curves with a distinguished map to projective line. We give tropical proof theorem H. Larson, showing that splitting have expected dimension general elements Hurwitz space. Our uses an explicit description on certain family curves. further show these connected in codimension one, and describe algorithm computing ...

To test the hypothesis that the H-2 polymorphism is adaptive, the degree of polymorphism of loci linked to the H-2 complex on chromosome 17 of the house mouse was compared to the degree of polymorphism of loci located on other chromosomes. Published theoretical analyses show that polymorphisms subject to natural selection usually reduce the polymorphism of linked neutral loci. The first test of...

This work focuses on a kind of fractals Parrondo’s paradoxial phenomenon “deiconnected+diconnected=connected” in an alternated superior complex system zn+1=β(zn2+ci)+(1−β)zn,i=1,2. On the one hand, connectivity variation Julia sets is explored by analyzing loci. other we graphically investigate position relation between Mandelbrot set and Connectivity Loci, which results conclusion that two tot...
