2. 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.
3. 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).
