The strain MAY not be true breeding for the
selected traits, but it will certainly help
make the population more uniform for that
trait.

CUBING AND BACKCROSSING

Our first cross between the Master Kush
plant and the Silver Haze is known as the F1
hybrid cross. Let us pretend for the moment
that both traits are homozygous for leaf
colour. The Haze is pale green the Kush is Dark
Green. Which one is MM or mm we do not know?
Until we see the offspring.

This F1 cross will result in hybrid seeds.
Now since M is dominant over m, then we will
know which colour is more dominant and from
which parent it came from. In the example let
us pretend that the overall results are pale
green. This means that the pale green allele is
dominant over the dark green.

M = Silver Haze pale green leaf trait is
dominant.
m = Master Kush dark green leaf trait is
recessive.
