TRANSGENE

• A transgene is a gene or genetic material that has been transferred naturally, or by any of a number of genetic engineering techniques from one organism to another. The introduction of a transgene has the potential to change the phenotype of an organism.

TRANSGENIC MALE STERILITY

• When the male sterility is induced by the techniques of genetic engineering, it is called as transgenic male sterility.

• It is heritable and basically comes under genetic male sterility.

• In this system, the two kinds of genes are involved.• One gene causes male sterility (integrated with genome of A line) while the other suppresses it (in R line).
