The following is from “Der Deutsch Kurzhaar, The German
Shorthaired Pointer” by
OUTCOMES OF
MATINGS, IN REGARD TO COLOUR AND PATTERN
(BLACK versus LIVER
AND SOLID versus NON-SOLID (“TICKED”))
The
following chart lists all the possible combinations of the nine basic
geneotypes for colour and basic patterning in the GSP. The basic patterning may be either solid or
non-solid. The amount of colour in the
white portions of the coat (i.e. whether it is ticked, roaned or clear white)
and the distribution of the solid areas (i.e. whether the dog has a “saddle”
and/or patches or no patches, or whether a solid has a white chest or toes or no
white at all) are not represented in the chart.
For the
nine possible geneotypes, see the illustration (Figure 12.1). Although that illustration and those which
follow, employ “piebald spotted” animals to represent non-solid (“ticked”), one
could substitute “Irish spotted” or “extreme white piebald” animals (see Figure
12.3) and the result would be the same, for all those versions of non-solid
(“ticked”) involve different alleles of the same gene “s”, and all are
recessive to “self” “S” gene for solid coloured coats. Whether “solids” have no
white in their coats or have patches on the chest and/or lower legs is not
important either as it does not affect the outcome. In my experience, homozygous solids tend to
have no white at all, but since heterozygous solids can also be devoid of
white, it is necessary to know the genetic background of an animal in order to
classify it correctly.

Since
there are only three geneotypes (liver/non-solid (“ticked”), heterozygous solid
liver and homozygous solid liver) and six possible combinations (see chart)
which do not involve one parent being black, only the first six apply to
American GSPs. Four of these are
illustrated.
The
last nine involve a parent which is homozygous for both black and solid
colouring. Since such animals are rare
and not favoured by breeders, no such combinations are illustrated. Combination 15 has been included, for
although it is rather unlikely that anyone would mate two solid blacks, this
combination provides the greatest number of possibilities.
The
percentages given represent the average outcome, so individual litters may vary
widely from the average. Nevertheless,
the possible outcomes are absolute, i.e. no other legitimate outcomes can occur
from the possible combinations. For
example, one can never obtain a solid from two ticked GSPs nor a black from two
liver-coloured ones (it is most important to remember the distinction between
“liver” and “solid” here, since many fanciers refer to solid livers as
“livers”).
The
abbreviations used in the chart are as follows:
|
lvr |
Liver
(colour) |
|
blk |
Black
(colour) |
|
tked |
“ticked”
(non-solid, pattern) |
|
sol |
Solid
(pattern |
|
het |
Heterozygous
(i.e. one dominant and one recessive allele) |
|
hom |
Homozygous
dominant … n.b. |
n.b. Because the alleles for
liver and for non-solid (“ticked”) which are recessive must be present in the
homozygous state in order for them to appear, I have not specifically referred
to them in the abbreviations. If an
animal is non-solid (“ticked”), or if it is liver coloured, it can be assumed
that it is homozygous for the genes for that pattern or colour. If, however, it is solid or black, it could
be either homozygous or heterozygous for the pattern or colour, hence the extra
classification in the chart.
A
marker (#) denotes those combinations which are illustrated, with drawings of
parents and offspring. Please note that
sex has no significance here. Either
parent could be of the colour/pattern used in the illustration.
