Negative additive effects
were found due to first and second major genes in the crosses during both years indicating that the major genes may affect the said trait adversely except in Bakhtawar-92 A- Frontana during first year where the additive effect
was positive due to the second major gene.
Only 23% of the variation among entries was attributable to the additive effect
for yield, whereas the minimal value for this same percentage for the other traits was 60% for spike length and the maximal value was 95% for leaf spot ratings (Table 1).
Since all subpopulations were derived from cycle 0, the definitions of the above terms are: A0 = contribution of additive effects
from Golden Glow at C0; D0 = contribution of dominance effects from Golden Glow at C0; ALI = linear function of changes in allelic frequencies influencing additive effects
in subpopulation I; DLI = linear function of changes in allelic frequencies influencing dominance effects in subpopulation I; DQ I = quadratic function of changes in .
Samples from more open waters did not cause this exaggerated additive effect
For example an additive effect
for lint percentage was significantly detected for all parents except P9.
There might actually be a beneficial additive effect
if the two agents are used in combination, although this hasn't been looked at.
Additionally, GX15-070 showed an additive effect
with doxorubicin, a chemotherapy agent.
The additive effect
of a QTL was calculated by PlabQTL as (mean of the homozygous MAM17-5 classmean of the homozygous Ogle class)/2.
Having two or three abnormalities had an additive effect
on the risk of a recurrent coronary event.
The significant glucose-lowering efficacy seen in this study suggests complementary mechanisms of action of sitagliptin and metformin resulting in an additive effect
when both agents are given together," said Barry J.
The three genetic parameters were defined as follows: m = the midparent value, a = the amount of variation among the means resulting from the additive effect
of the genes, and d = the amount of variation among the means resulting from the dominance effect of the genes.
While rest of the combination showed additive effect
For the multi-chem approach, an additive effect
Additive X additive effect
(i) of the major genes plus polygene was found to be 44.
The term additive effect
, which comes from biological and chemical research, refers to combining multiple elements so that the results equal the sum of each element's effects.
