Revisiting "Using Irises with SA/,,,,"


Kelly and others,
 
Let's try this again and get it right this time.  Pierre Rutten kindly and gently reminded me of the reduction division to the haploid number before we get to Punnett Squares, etc.  I seem to be operating in a fog right now and slid right by that most basic bit of genetic know-how--and there's a cause.  I've been right on the edge between a nasty bronchitis and crisis pneumonia for several days--as if I needed an excuse.  These things go with the turf over which I've traveled the past couple of years...this makes the third time since June.
 
So....the possibilities with one factor in a diploid are A, a.  There are only four squares in a single factor array in diploids.  With two factors taken together one has on each side AB, Ab, aB, ab, so the square has sixteen possible outcomes.
 
With tetraploids, the haploid number gives two of a factor, so the one factor condition has AA, Aa, and aa--nine possible outcomes for the single factor in the array.  With two factors it gets a little complicated--provided the factors are inherited independently.  The possible gametes are AABB, AABb, AaBB, AaBb, Aabb, aaBb and aabb, giving an array of forty-nine outcomes--with only two factors.
 
The rest of what I said, I believe, stands as stated.  Only those assertions concerning the numbers involved were grievously in error.  When I'm wrong, I enjoy doing it up fine. 
 
Better yet, read TWOI.  It will give you a headache, I guarantee.
 
On another track,  I have transferred all our messages to a set of Word files through post # 1017, and have begun editing them, deleting extraneous advertising materials, and so on.  Where messages are copied in their entirety I am taking substantial liberties in removing the duplication or selecting out the portion of the previous post being responded to.  If anyone objects to this approach, please let me know offline.
 
I'm still here, still plodding along.  Y'all are doin' fine from what I can see...we're getting close to a workable consensus on what SA's to use.  We can then concentrate on what "ledge," non-ledge and known breeders that have been reported to do this or that we may want to use. 
 
If anyone wants to see the extent of Sass ancestry in pinks, look at the pedigree/family tree of CHERIE on the HIPS site.  FANTASY, mentioned by Sharon McAllister as one of the types having the ledge under the beard, is one of the parents of Cherie, so the entire known ancestry is right before our eyes.
 
That (Golden Eagle x 39-62) cross behind Hall 42-07 yielded several other seedlings than the one showing in the tree behind Cherie.  The earliest Hall seedlings used in Utah were mostly or entirely sibs to that seedling if I remember correctly.
