The following is from  Der Deutsch Kurzhaar, The German Shorthaired Pointer” by Georgina M. Byrne.   This is probably the premier of all GSP books and a must for any GSP breeder.

OUTCOMES OF MATINGS, IN REGARD TO COLOUR AND PATTERN

(BLACK versus LIVER AND SOLID versus NON-SOLID (“TICKED”))

 

Georgina Byrne

 

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.

AND BASIC COAT PATTERNING (SOLID AND NON-SOLID)

12.1a  bbss… Liver & non-solid (“ticked”)

12.1f  BBSs… Solid black, heterozygous for solid (carries non-solid (“ticking”) but not the liver colour)

12.1b  bbSs… Solid liver, heterozygous for solid, carries non-solid (“ticking”)

12.1g  BbSs… Solid black, heterozygous for both solid and black (carries both non-solid (“ticking”) and the liver colour)

12.1c  bbSS… Solid liver, homozygous for solid

12.1h  BbSS… Solid black, homozygous for solid, heterozygous for black

12.1d  Bbss… Black and non-solid (“ticked”), heterozygous for black (carries liver)

12.1i  BBSS… Solid black, homozygous for both solid and black

12.1e  BBss… Black and non-solid (“ticked”), homozygous for black

THE DISTRIBUTION OF COLOUR VERSUS WHITE AREAS

12.3a    SS or Ss

12.3b   sisi

12.3c    spsp

12.3d    swsw

12.3a  S… self (solid) coloured.  White, if present, only on the chest and feet or lower legs. 

12.3c   sp… “Piebald spotted”.  Patches of colour on the head and body.

12.3b  si… “Irish spotted”.  White on legs, chest and neck.

12.3d  sw… “Extreme white piebald”.  Coloured areas confined to the head and base of tail.

 

 

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.
