population got this disease?
The same question applies to cannabis
breeding. If purple bud colour 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 show a tendency to spread
over a whole population. Also there is no logic
behind the idea that a recessive trait should
die out.
Gene frequencies can be in high ratios or
low ratios no matter how the allele is
expressed. The allele can also change,
depending on certain conditions. It is the
changes in gene frequencies over time that
result in different plant characteristics.
