Sentences with phrase «phenotypic variance»
"Phenotypic variance" refers to the differences or variations observed in the physical traits or characteristics of a group of individuals. It relates to the diversity seen in how people look or behave, which can be influenced by genetic factors as well as environmental factors. Full definition
In the German Shepherd, HD polygenic variance as a proportion of phenotypic variance changed the least compared to other breeds, that is, from 0.23 to 0.10 (Table 1), and in the Rottweiler it changed the most, that is, from 0.36 to 0.11 (Table 4).

In addition, behaviour - genetic analyses usually employ main effects models dividing up the total phenotypic variance into additive (or dominant) genetic, shared and non-shared environmental components.
This allele confers increased adiposity in male animals compared to AKR / J, and accounts for 11.7 % of the phenotypic variance in male inguinal fat pad weight (percentage).
We identified 307 conditionally independent single - nucleotide polymorphisms (SNPs) that attained genome - wide significance at 203 loci, explaining approximately 12 % of the phenotypic variance.
It is concluded that there is true environmental mediation from family maladaptation, operating as a shared effect, which accounts for 3 · 5 % of the phenotypic variance.
However, the real problem might be that more complex behavioural phenotypes are affected by many genes, each with only a small effect accounting for only 1 % or even less of the phenotypic variance [81], therefore inadequate statistical power is a serious problem.
Biometric analyses showed that these multi-source measures of childhood impulsivity and inattention were highly heritable, with genetic variance accounting for 70 - 80 % of the phenotypic variance in many of the models.
