Negative and significant values of h (dominance) showed a major role of dominant gene
action in the inheritance of this trait in all the crosses except, PS-Pop-29-2-1 x BD- Pop-2-1-2.
effects were more significant, in maize grain yield and kernels/row, while, additive gene effects were more important for kernel rows/ear and 1000-kernel weight.
"We have genetically engineered the bacteriophages so that once they infect the bacteria, they transfer a dominant gene
that confers renewed sensitivity to certain antibiotics," Qimron said.
The resistance of KS99WGRC42 to Hessian fly is controlled by a single partially dominant gene
located on chromosome 1AS.
A dominant gene
, such as that for brown eyes, will show up if only one of the pair is present.
Wang suggested that the Qinling pandas carry a dominant gene
for black fur and a recessive gene for brown fur.
GS-154, PI 633834) (Triticum aestivum L.), is a genetic stock carrying a dominant gene
Ba, causing blue color in the endosperm of the caryopsis.
Not all carriers of a defective gene get the condition: if it's recessive it can be masked by a healthy version, whereas a dominant gene
will always show up.
"Black is the dominant gene
in poodles so this is not unusual but the exact outcome would depend on the genetic history of the father and the mother," the Telegraph quoted Beverly Cuddy, editor of Dogs Today, as saying.
Takahashi and Abe (1994) further found that one of the genes for tolerance was closely associated with a dominant gene
for late maturity, the recessive allele of which was involved in floral induction under artificially induced long days by means of incandescent lamps.
If, as previously suggested, the long arm of chromosome 2A in Chinese Spring carries a partially dominant gene
for susceptibility, this [F.sub.1] reaction can be explained by assuming that chromosome 2A in Red Chief also carries that gene for susceptibility.
Thirty-two families segregated resistant (normal growth) and susceptible (stunted) plants versus 31 families in which all seedlings were susceptible, indicating a single partially dominant gene
for resistance in CI 3984.
