Inheritance patterns in the latter can be explained by a polygenic heterogeneity model, involving a dosage effect resulting from the combined effect of both common and rare variants of susceptibility genes. The evidence thus far suggests that ion channel dysfunction constitutes a key mechanistic pathway...
Traits that do not follow Mendelian inheritance patterns and are derived from any combination of multiple genetic factors, environmental factors and their interactions. Single nucleotide variants (SNVs). Single base pair positions in the genome where there is variation across individuals. SNVs need not...
I started blogging to teach people and literally “explain” about genetic genealogy – which is why I selected the name DNA-eXplained. Over time, it has also been nicknamed DNAeXplain, which is fine. I hoped to be able to answer questions once, with graphics and examples, instead of over...
Ordination plot for the first two principal component axes resulting from a discriminant analysis of principal components (DAPC) for each individual, ellipses indicate their assignment to the genetic clusters inferred. The low-right graph indicates the variance explained by the principal component axes ...
(or internally via resampling). Since different studies use different variables, clustering techniques, and several clusters, the results tend to vary. This may in part be explained because similar data is not always available and selection bias may occur (e.g., patients withcognitive impairment...

Inheritance In order for someone to exhibit the autosomal recessive trait of blueness due to Methemoglobinemia, they must inherit a copy of the gene from BOTH PARENTS. That’s why this trait is so rare. If the parents have only one copy each, they are carriers and will not have the cond...
gigas is known to have a high genetic load [42], such distortions in these bivalves have been explained by zygotic viability selection due to the presence of deleterious recessive genes [9, 11, 12]. Segregation distortions reported here may also be attributed to the presence of deleterious ...
(Supplementary Fig.9). Overall, the predictive power of PRS is not high, in line with earlier discoveries involving raw imaging-derived phenotypes, as demonstrated in ref.13. The authors developed PRSs for seven selective brain regions, which explained roughly 1.18–3.93% of the phenotypic ...
explained = 0.20%) and suicide thoughts (maximum variance explained = 0.13%) (Fig.3). Although the PRS forself-harm behaviourdid not predict NSSH in our sample, the PRS forself-harm behaviourwas predictive of broad sense self-harm (regardless of suicidal intent; maximum variance explained ...
