For micropropagation and genetic transformation it is necessary that plants regenerated from callus culture are genetically stable without any significant phenotypic variation.
They repeated the experiment using mice that had been genetically engineered without one type of receptor.
Garden centres have been ordered to withdraw orange petunias from sale over concerns that they may be illegal because they were genetically modified without authorisation.
Furthermore, most TALEN transformed cell lines were found to be genetically homogeneous without the need for re-plating, which greatly facilitates the screening process.
But there is no similar standard specifying what percent of seeds in a bag of nonmodified seeds can be genetically engineered without requiring the whole bag to be rejected.
Idiopathic or primary headache syndromes are disorders in which there is a temporary or permanent dysfunction of the central nervous system, often genetically determined, without apparent organic lesion.
Scientists compared urination patterns, both volume and frequency, in normal mice and in mice genetically engineered without two circadian genes, Cryptochrome-1 and Cryptochrome-2, resulting in dysfunctional circadian rhythms.
In this subtype, AR has undergone a dominant-negative, loss-of-function mutation even though AR is genetically amplified without the patient ever receiving androgen ablation therapy.
Secondly, one may speculate that these Jewish communities were established by males who recruited local women in a number sufficient to make the community genetically sustainable without significant subsequent introgression.
