Non-random mating and Natural selection:
This suggests that something external may influence a
population to a stage where mating is not random. If some flowers
develop earlier than others then they will gather pollen earlier than the
rest. If some of the males release pollen earlier than others then the
mating is not random. Or maybe all males release their pollen earlier
resulting in some of the later flowering females ending up as a
sinsemilla crop. This means that these late flowering females will not
make their contribution to the gene pool. Again equilibrium will not be
maintained.
With regards to natural selection the environment may cause
a problem with a section of plants. If this section does not survive then
they will not be able to make a contribution to the gene pool. If this is
the case and if selections are made so that other plants do not make a
contribution then we know that trait frequencies can be controlled to a
certain degree. And the ability to control the frequencies of a trait is
what BREEDING IS ALL ABOUT.
HOW TO TRUE BREED A STRAIN
Breeding cannabis strains is all about manipulating gene
frequencies. Most strains that are sold by reputable breeders through
seed-banks are very uniform in growth. This means the breeder has
attempted to lock certain genes down so that the genotypes of those
traits are homozygous.
If we can imagine for a moment that a breeder has two strains
- Master Kush and Silver haze. The breeder lists a few traits that they
like. * Donates the trait that they like.
