and a bit more
about this subject matter.
Gregor Mendel (1822-1884) was an Austrian monk who
discovered the basic rules of inheritance by analyzing results from his
plant breeding research programs.
He noticed that 2 types of Pea plants gave very uniform
results when breed within their own gene pool and not with one
another. The traits he noticed where:
(This is not a Punnett square. Just an example to show the different
phenotypes seen in two different Pea plant strains.)
He noticed that the offspring all carried the same traits when
they breed in with the same population or gene pool.
Now since there where no variations in with each strain he
guessed that both strains where homozygous for these traits. Because
the pea plants where from the same species Mendel guessed that either
the Solid seed shells where recessive or the wrinkled seed shells where
recessive. So he used the genotype notations (SS for solid, ss for
wrinkled). He knew that they could not be Ss, because one lot did not
produce any of the other strain’s phenotypes when they breed within
their own gene pool.
Let’s explain this via 2 basic Punnett squares where SS = Pea plant#1
for the trait of ‘solid seed shells’ and ss = pea plant#2 for the trait of
‘Wrinkled seed shells’.
That was Pea plant#1 results. All the offspring will be SS.
That was Pea plant#2 results. All the offspring will be ss.
The First Hybrid Cross:
Mendel made his first hybrid cross between the 2 strains. The
results where all solid seeds! Here is the chart below.
Now up until this point he did not know which trait from
which plant was recessive or dominant. But since all the seeds where
solid, then he knew that Pea Plant#1 contained the dominant genotype
for seed shape and that Pea Plant#2 contained the recessive genotype
for wrinkled seeds. Also he knew that Pea Plant#2 contained the
recessive genotype for seed shape. This means that in future TEST
CROSSES with other pea strains, he could determine if a seed shape
trait is Homozygous or Heterozygous because he had identified the
recessive trait (ss).
Remember the rules of test crosses to determine this Here
they are again.
1. The plant with the dominant trait is always crossed with an
organism with the recessive trait.
2. If ANY offspring show the recessive trait, the unknown genotype is
3. If ALL the offspring have the dominant trait, the unknown genotype
is homozygous dominant
4. Large numbers are needed for reliable results.
So the offspring from the last Punnett square where all Ss.
When he crossed 2 parents from the bunch of offspring he got the
What he has done here is to mate 2 individuals that are heterozygous
(e.g., Ss) for a seed shape trait. In this group the resulting offspring
This means that:
25% of the offspring are homozygous for the dominant allele (BB).
50% are heterozygous like their parents (Bb) and
25% are homozygous for
I would suggest Sensi Seed's "Shiva Skunk" (NL#5 X SK#1). Very close nodes, sweet, fragrant smoke. Great
yield and it will finish in about 55 days. Very high calyx to leaf ratio. Great resin production. I grew this strain
for 4 years in a SOG format and I was very, very impressed. Very easy to grow, cloning is a breeze. Only
problem I had is that after about 3 years the high started to get a little weaker and the yields did go down
slightly. It just seemed to lose some of its vigor. So if you used it for 2 years or so, it could very well be what
you are looking for." -imposter
“The most potent I have had to date is probably Shiva Skunk, a close relative of Silver Pearl. This variety is
hallucinogenic. Not to be smoked if you have to operate any machinery within the next several hours.” – Hyde
