complex locus
3.1. The segregation of Hyg-resistance of the progenies of 29 T1 plants is complex, only thatof eight plants fixed the Mendelian fashion of 3:1, the rest deviated the ratio. There was singleinsertion locus in the chromosomes of the transgenic plants. The percentage of Hyg-resistanceplants is lower than expected, possibly due to the lost or silence of foreign genes.
