In some heterozygous conditions, both the dominant and recessive allele phenotypes are expressed. From a molecular viewpoint, the relationship between the normal allele and the mutant allele is best described as codominant. This means that, at the molecular level, neither allele masks the expression...

The results confirmed that the identified SNPs are polymorphic not only in the dog breeds, but also in wolves, however allele frequencies differed among the investigated breeds as well as between dogs and wolves. These results have recently been confirmed and extended (Bence et al., 2017) by ...
2015). In order to ensure that any potential substructure within continental taxa is detected, we ran independent population-structure analyses once for all individuals and once including only O. mellianus, O. t. traillii, and O. t. robinsoni. Finally, unbalanced allele-sharing in a four-...
These examples demonstrate that if the expression level of a gene product is tightly linked to growth fitness and cannot meet the needs for maximum growth, gene amplification can occur through adaptive evolution. In diploids, haploinsufficiency describes a state whereby one allele at a heterozygous ...
Therefore, genetic ancestry has emerged as an appropriate measure to capture differences in human genetic variation, which is best described along a continuum rather than in discrete categories, and thus explicitly captures the impacts of human histories that have led to different forms of genetic ...
Tobacco (Nicotiana tabacum L.) is an important industrial crop plant. However, it efficiently accumulates metals, primarily cadmium (Cd) and also zinc (Zn)
The file passed to DeCiFer via--segfile, which specifies the allele-specific copy number per segment, is the same as thebest.seg.ucnfile used by thevcf_2_decifer.pypython script that generates the input files for DeCiFer. Please simply specify the location of this file. ...
The tokogenetic history of an allele or gene copy, from a particular gene, is termed a gene genealogy or gene lineage. Figure 19.3D and E illustrate a gene lineage showing the transfer of a unique mutation from parent to offspring in sexual and asexual systems, respectively. Individual gene ...
Pacific spider mites, Tetranychus pacificus McGregor, were grown on oranges, as described by Scriven and Fleschner (1960). Spider mites were brushed off from the oranges and provided to Phytoseiulus spp., which were reared on an artificial plastic substrate. This method reduces the problems ...
