Nine other QTLs were detected for either or both the testcross and [H.sub.MP], indicating that they are overdominance
QTLs having significant dominance effects and little additive effect.
In some cases, it could suggest a rapid response to the breeding procedure or the trait involved was being highly influenced by an environmental factor or it could be an indication of overdominance
situation of dominant alleles.
Due to the strong overdominance
observed in F1 mice infected with 102 parasites (Figure 6(c))and to a wide range of other challenge doses (data not shown), a segregating population of 242 mice was constructed by backcrossing F1 mice with the susceptible parental [L.sub.III] line (Bc-L).
1991) studied the quantitative traits in bread wheat using graphic analysis, and showed that genes control the traits plant height and spike length by incomplete dominance, weight of 1000 seeds by complete dominance, number of seeds per spike, number of spikelet per spike, and seed weight per spike by overdominance
. The present research has been carried out to study the genetic control manner of the traits of yield and estimate the value of different genetic parameters in these traits.
With respect to what we have called the first level of analysis, that referring to the segments of the interactivity of the pairs during the task of text production, the overdominance
of draft editing can be explained by its accumulating effect during each stage of the tutoring process.
In the present study, low x low gca combination also produced hybrids with high sea and this could be attributed to overdominance
or epistatic gene action.
The use of minimal visual cues with the auditory-verbal method is supported by physiological studies that have shown that in deaf animals, an overdominance
of visual inputs to the auditory cortex that lead to an incorrect balance between the auditory and visual systems needs to be corrected.
Increased run production, a new generation of high-profile managers, a new, young commissioner, the increased power of the players' union, revamped league formats and the introduction of playoffs, new multipurpose stadiums--all these coalesced to propel the national pastime beyond its lethargy of 1968, the most visible symptom of which was the overdominance
of pitching, and it was this amalgamation that led baseball on the path to the current modern game.
This finding further suggested that an overdominance
of any single terminator in the extension mixture promotes misincorporation.
of Computers." Educational Leadership 63, no.
He suggested the term overdominance
for superior heterozygous loci and suggested recurrent selection with early testing (unfinished inbreds) for specific combining ability as a procedure to breed for such gene action (Hull, 1945, 1952).
The feature was the result of expression of a normal copy of a specific gene from the mother and a mutated copy of the same gene from the father--an inheritance pattern known as paternal polar overdominance
. This was its first known occurrence in a mammalian species.
