keep will actually be kept in our breeding process?
This is where the test cross comes in. If we create seeds from
a strain that we bought in a seed-bank how can we be sure that the
offspring will have the character that we like? Well the facts are this.
If the trait(s) we wish to continue are Homozygous Dominant (BB) in
both the parent plants then there is no way we can produce a recessive
genotype for that trait in the offspring. We already explained this in
the previous section.
Let's prove this:
Look! It is impossible for the recessive trait to appear.
And if both parents contained the recessive trait we can not
produce the dominant trait. Let us see this in action too.
There we proved that too.
So now we are starting to understand that in order to breed a
trait properly we must know if it is Homozygous or Heterozygous or
Homozygous Recessive before we can understand what it is we are
doing and PREDICT THE RESULTS BEFORE THEY HAPPEN. And
