Okay...according to Mendel square....if you bred half brother (same mother) to
half sister (same mother) you would get: 25% of half sires no common mother,
25% with sire of half brother and common mother, 25% with sire of half
daughter's sire with common mother and 25% of ALL common mother....so the
answer is 25%. Heterozygous for common mother is 75%....but pure mother is 25%!
Thats the answer!!! Angela

Subject: [ SHOWGSD-L ] Question/ Grand Dam
Reminds me of a song that was going around when I was a kid titled..... 'I'm
My Own Grampa'...... <G>
She is contributing 1/2 of the total.......but Isn't it 25% less of NEW genes
received in that litter....or 25% more of the SAME genes you would have gotten
anyway? Just getting those same genes....again. Doubling up on her, means
less "new" genes coming in since there is one less dog bringing in more new
genes? ( not talking about traits or dominant or recessive.......just
percentage ) It is hard for me as a breeder to look at it this way...as a
"percentage".....as we are always concerned with traits, dominant genes and
recessives that we use to improve or to stay away from....
Let's just say each dog has 1,000 genes ( yeah yeah I know..... not even close
) <G> but we have to have some kind of 'even' starting place to get this
picture. Like 1,000 building blocks. It would be almost like not getting
25% new genes available......or blocks. <G>
You are getting the 1,000 of the Grand Dams genes twice. ( you don't get MORE
new genes from her each time she appears ) Same 1,000 genes, but instead of
4,000 all new genes in the breeding from four lines ( or four dogs )...you are
getting 3,000 new genes totaled together from three lines. ( or dogs ) One
1,000 being a repeat of her already 'donated' 1,000. In other words...she
can only bring in her 'original' 1,000 genes. If in this theory they each
have 1,000 DIFFERENT genes each... all different from each other. You just
made the gene pool SMALLER, instead of one dog being a "bigger
percentage".....?? So you do not have 50% MORE genes from her. You still
just have her 1,000 ..( you have 25% less of 4,000 possible new genes than from
an outcross on all four dogs...??

Yes genes have different traits and expressions , I'm not saying the genes from
grandmother are exactly the same, I'm just saying grandmother is contributing
50 % of the total! In a total out cross both parents contribute 50% which means
a litter of two non related parents are getting 25% from the 4 grandparents....
because each pup gets 50 % from each parent, if one grandparent appears on each
side of the pedigree that grandparent is contributing a higher percentage of
genes.... if I were in a classroom I would put a diagram on the board! lol Ed

No....
don't forget that there are grandsires involved.
And you must consider that different traits have
different modes of genetic transmission....some are
dominate and some are recessive.

Good article on canine genetics.

Subject: [ SHOWGSD-L ] Question
First let me wish everyone Merry Christmas, yes in deed today IS Christmas, but
I won't get into that today.... my question is if you have a puppy who is out
of a half brother, half sister breeding both having the same mother, is the
puppy genetically 50 percent of the grandmother.... and if so, basically the
grandmother is genetically also the mother... hard to ask this via email. Been
arguing this with my wife for two days! Ed
