First High Density Linkage Map and Single Nucleotide Polymorphisms Significantly Associated With Traits of Economic Importance in Yellowtail Kingfish Seriola lalandi

Front Genet
PMCID: 5914296
PMID: 29719550
DOI: 10.3389/fgene.2018.00127

[…] calling consistency was evaluated and reported for each snp (ranging from 90 to 100%, average 98%). the raw sequence data has the accession number srp130211., the linkage maps were constructed using lep-map3 software ()., first, the genotypes were converted to genotype likelihoods (posteriors) using linkage2post.awk script provided with lep-map3. then the missing parental genotypes were imputed […]


Accuracy of Genomic Evaluations of Juvenile Growth Rate in Common Carp (Cyprinus carpio) Using Genotyping by Sequencing

Front Genet
PMCID: 5859378
PMID: 29593780
DOI: 10.3389/fgene.2018.00082
call_split See protocol

[…] allowing for a maximum overall genotyping error of 4%. the pedigree obtained was further validated for possible erroneous assignments using fimpute ()., linkage map construction was performed using lep-map v2 (). snps with maf <0.05 in individual families and those deviating from expected mendelian segregation (p < 0.001) were excluded. linkage groups were formed using a minimum lod […]


Accounting for Errors in Low Coverage High Throughput Sequencing Data When Constructing Genetic Maps Using Biparental Outcrossed Populations

PMCID: 5937187
PMID: 29487138
DOI: 10.1534/genetics.117.300627

[…] applicable to outcrossed full-sibling (full-sib) families. recently, two software packages have been developed for performing linkage mapping in full-sib families using sequencing data. these are lep-map (, ) and highmap (), both of which address the computational problem associated with high-density maps but are not specifically designed to handle low coverage sequencing data., another […]


A Genome Wide Association Study for Host Resistance to Ostreid Herpesvirus in Pacific Oysters (Crassostrea gigas)

PMCID: 5873916
PMID: 29472307
DOI: 10.1534/g3.118.200113

[…] as good quality (‘polyhighresolution’ and ‘nominorhom’ categories), from ∼40 k putative available for c.gigas on the array, and retained for downstream analyses., linkage maps were constructed using lep-map 3 (). families used for the generation of this map were assigned using cervus () as described by , and further confirmed through the ibd module in lep-map3. putative erroneous or missing […]


Using Linkage Maps as a Tool To Determine Patterns of Chromosome Synteny in the Genus Salvelinus

PMCID: 5677171
PMID: 28963166
DOI: 10.1534/g3.117.300317

[…] package in stacks (default parameters), and snps scored in <80% of f1 samples removed. these filtering criteria produced a total of 12,961 candidate snps., linkage maps were constructed using lep-map v 2.0 (). separate sex-specific maps of female segregating and male segregating loci were constructed because of the pronounced heterochiasmy exhibited by salmonids (). pairwise estimates […]


Construction of a high density linkage map and fine mapping of QTLs for growth and gonad related traits in blunt snout bream

Sci Rep
PMCID: 5395971
PMID: 28422147
DOI: 10.1038/srep46509

[…] the flanking sequences of all 14,648 snps were listed in ., based on a double pseudo-test cross strategy, a high-density rad-based snp genetic map of m. amblycephala was first constructed using lep-map. a total of 14,648 segregating snps were successfully classified into 24 lgs (). the maternal map contained 9,531 snps with a total genetic distance of 2390.06 cm; the length of each lg […]
