Estimates of genetic parameters following Hayman's method showed a high value of additive gene effects for callus growth, which were recognized as incomplete dominance and negative action. |
Some alleles do not have complete dominance and instead have incomplete dominance by expressing an intermediate phenotype, or codominance by expressing both alleles at once. |
In the control of spike length inheritance, incomplete dominance and additive effects were observed. |
Observers typically described dominance in these locations as being more immediate and less ambiguous, with less incidence of incomplete dominance. |
This is just one of many examples of incomplete dominance, in which the hybrid does not resemble either pure-breeding parent. |
In something called incomplete dominance, both the dominant and recessive alleles are expressed in the offspring. |
