They work just like dominant and recessives except that there
are more than two options. If a gene is dominant over another gene, it
will win. Just like a dominant will win a recessive.
HARDY-WEINBERG EQUILIBRIUM
Introduction:
An understanding of breeding concepts requires a basic
understanding of Hardy-Weinberg's Equilibrium. Breeding depends
upon the knowledge of population genetics. To understand the value of
the H/W Equilibrium, you may have asked yourself a question like this
before...
“If certain diseases are a dominant trait, then why haven't
large sections of the population got this disease?”
The same question applies to cannabis breeding. If purple bud
color is a dominant trait then how come my offspring from the purple
bud strain do not have purple buds? Or, I have been selecting Indica
mothers and cross breeding them with mostly Indica male plants but I
have some Sativa leaves. Why does this happen? Hardy-Weinberg's
Equilibrium will help you to understand these questions and there
answers.
Okay, first of all these questions reflect a very common
misconception. That misconception is that the dominant allele of a
trait will always have the highest frequency in a population and the
recessive allele will always have the lowest frequency.
There is no logic behind the idea that a dominant trait should
