Background: Legless lizards, the slow worms of the genus are forming secondary contact zones within their Europe-wide distribution.
Methods: We examined 35 populations of and to identify the level of morphological and genetic divergence in Poland. We applied a conventional study approach using metric, meristic, and categorial (coloration) features for a phenotype analysis, and two standard molecular markers, a mitochondrial (NADH-ubiquinone oxidoreductase chain 2; ) and a nuclear (V(D)J recombination-activating protein 1; ) one.

This study aimed to investigate whether genes with different modes of inheritance differ in the presence of promoter-enriched CGI loci. For each autosomal chromosome, the author searched for variations in the total number of diseases' phenotypes with autosomal dominant (AD) and recessive (AR) inheritance for a list of promoter-poor CGI (CGI-) and promoter-enriched CGI (CGI+) genes using the OMIM database. Then, the CGI- and CGI+ genes displaying random allelic or bi-allelic expression were examined.

Introduction: Useful germplasm for citrus breeding includes all sexually compatible species of the former genera , and , now merged in the single genus. An improved knowledge on the synteny/collinearity between the genome of these different species, and on their recombination landscapes, is essential to optimize interspecific breeding schemes.
Method: We have performed a large comparative genetic mapping study including several main clades of the genus.

Background: As part of stock enhancement programs for marine fishery species, the stocking of hatchery-produced seedlings into sea areas has been implemented worldwide. DNA markers are vital for responsible stock enhancement practices that aim to conserve the genetic diversity of recipient wild populations. We report novel single-nucleotide polymorphism (SNP) markers and multiplex SNP panels developed for the west Pacific pen shell Atrina lischkeana (Clessin, 1891), a large bivalve that is expected to be a subject of stock enhancement activity as the natural resource has dwindled, especially in Japan.

Herbicide application to plants heterozygous for herbicide resistance results in distorted segregation favoring resistant allele transmission resulting in a conditional gene drive. Brassica napus plants heterozygous for an allele conferring sulfonylurea resistance at a single locus exhibit normal Mendelian inheritance. However, following application of the herbicide, highly distorted segregation of herbicide resistance occurs among progeny.
