Monitoring Three Plasmopara halstedii Resistance Genes in Iranian Sunflower Inbred Lines
Background: Downy mildew caused by Plasmopara halstedii is one of the most devastating diseases of sunflower worldwide. So far several dominant resistance genes designated as Pl have been identified and their molecular markers linked to these genes are available. However, no information on the resistance genes is available in Iranian lines. Objective: In this study, the presence of three map-b...

متن کاملSelected Lines and Inbred Strains
In their quest to elucidate the genetic influences contributing to alcoholism, researchers have long used selected lines and inbred strains of rodents. Selected lines are obtained by repeatedly mating those animals within a population that show extremely high or low values of the desired trait. Inbred strains are generated by mating male and female siblings, irrespective of any particular trait...
متن کاملChange in Recessive Lethal Alleles Frequency in Inbred Populations
In a population practicing consanguineous marriage, rare recessive lethal alleles (RRLA) have higher chances of affecting phenotypes. As inbreeding causes more homozygosity and subsequently more deaths, the loss of individuals with RRLA decreases the frequency of these alleles. Although this phenomenon is well studied in general, here some hitherto unstudied cases are presented. An analytical f...
متن کاملGenetic studies in NZB mice. V. Recombinant inbred lines demonstrate that separate genes control autoimmune phenotype
The genetic basis for autoimmunity in NZB mice has been investigated through analysis of recombinant inbred lines produced by mating NZB mice with two different non-autoimmune strains. Several genes (at least six) were found to be necessary for the production of eight traits characteristic of the NZB mice that were studied. No fundamental genetic defect (an "autoimmunity gene") was identified t...
