I don't think anyone answered Phillip's original question, so I'll give it a
go.
So, Jean Ernest, do you think that FC Gwendellin carries the yellow
factor>then? Since my stallion Smedsmo Graen already has one yellow
offspring, we>know he carries the yellow factor. What do you suppose the
chances are for>getting a yellow dun foal from this mating?
I went to the pedigree for Smedsmo Graen and checked for the yellow progeny,
which is Yenna, out of a white mare. I think the conclusion you can draw
about Smedsmo Graen is that he carries a recessive red gene and passed it on
to Yenna. Yenna's dam must also have contributed a red gene, as well as a
creme gene, to create the yellow dun (gul). I should say the creme gene
most likely came from the dam, as there is no indication of any ulsblak or
gul in Smedsmo's lineage, where color is indicated. And the creme gene can
go undetected in gra.
Gwendellin's pedigree tells us she is a white dun (bay or brown base color +
dun dilution + one creme dilution). Her two listed progeny were brown dun
and white dun. Her pedigree, where color is listed, does not show any red
duns; however, that does not mean that she can't carry one red recessive
gene. But currently there is no indication she carries a red gene, unless
she were to produce a red or gul, or even a cremello kvit, foal.
Conclusion: Smedsmo Graen does not carry the yellow factor, but carries the
red factor. Gwedellin may or may not carry the red factor, but can
contribute a creme gene to her offspring. And a mating between Gra and
Ulsblak can produce brown dun, ulsblak (white dun), red dun, yellow dun, gra
or kvit. That last bit of info from Tor Nestaas' chart on colors.
Did I get that right, Jamie? :^)
