Golden rice differs from its parental strain by the addition of three beta-carotene biosynthesis genes.
The study raises the question of whether a vaccine that works against parental strains will also protect against their hybrid offspring, researchers said.
And, the chromosomes that are lost from an aneuploid nucleus during its reversion to a euploid could be a mixture of those in the parental strain.
As an example of independent assortment, consider the crossing of the pure-bred homozygote parental strain with genotype " AABB " with a different pure-bred strain with genotype " aabb ".
A and a and B and b represent the alleles of genes A and B . Crossing these homozygous parental strains will result in F1 generation offspring that are double heterozygotes with genotype AaBb.
Each new strain is given a unique number and registered with the U . S . EPA and allowances may be given for genetic modification depending on " its parental strains, the proposed pesticide use pattern, and the manner and extent to which the organism has been genetically modified ".
