whether or not gene frequencies have changed in
a population.
A population is a group of individuals of
the same strain or species, [such as cannabis
Indica or cannabis sativa (species), or Skunk#1
and Master Kush (strains of a species)], in a
given area whose members can interbreed with
one another. This means that they share a
common group of genes. This common group of
genes is known as the GENE POOL.
Each gene pool contains all the alleles for
all the traits of all the population.
For a step in evolution to occur some of
the gene frequencies must change. That is why
we have different types of cannabis plants.
The gene frequency of an allele refers to
the number of times an allele for a particular
trait occurs compared to the total number of
alleles for that trait.
Gene frequency is calculated as follows.
The number of a specific type of allele,
divided by, The Total number of alleles in the
gene pool.
The Hardy and Weinberg principal describes
a theoretical situation in which there is no
change in the gene pool. This means that there
can be no evolution.
