COAT INHERITANCE

COAT COLOUR INHERITANCE CHART

The figures below are based on the probable percentages from a litter of four puppies in each possible mating.

Regarding the grey Tervuerens - the exact genes have not yet been iscolated so I have left the simplistic examples below until the genes can be identified. Even though the genes which produce the grey Tervueren have not been iscolated, I have left the basic reference in regarding probable outcomes from litters where grey is known to be possible.

It has been genetically proven that the Belgian Shepherd has the recessive black in its array of genes, and to a much lesser degree, black and tan.

I do not claim to be an expert on the genetics of coat colour inheritance in the Belgian Shepherd - far from it. I did however want to set out a simplistic chart for those just learning to follow. However good friend Lee Jiles has made me realise that not only was there holes and errors in my firstchart - but also that I needed to go a little deeper to make it a truly useful tool. I will add further links to this page as I find relevant reference tools. If you know of useful and informative links relevant to the Belgian Shepherd please email them to me at belgianshepherds@bigpond.com.

Both parents are dominant black and therefore all of their puppies will be pure Groenendael. Groenendael who are dominant black are known as Genotypical.

One parent is pure Groenendael & the other appears pure but carries the Tervueren gene.  Half of the puppies will be pure Groenendael & half will lappear pure Groenendael but will carry the Tervueren gene. Groenendael carrying the Tervueren gene are referred to as Phenotypical.

Both parents appear to be pure Groenendael but each carries the Tervueren gene.  Results could be one puppy pure Groenendael, two looking pure Groenendael but carrying the Tervueren gene, & one Tervueren. The proportion thus being 1:2:1

One parent is red Tervueren (which is dominant to grey) and the other is grey Tervueren (which is recessive to red).  Each puppy will be red Tervueren but carry the recessive grey gene.

One parent Groenendael but carrying the Tervueren gene and the other parent grey Tervueren.  These combinations can be muddied.  For example the Tervueren gene carried by the Groenendael may include both red and grey, therefore you may get a mixture of all or any of these puppies Unless you know for sure what is behind the Tervueren gene, you could get any of these combinations.  The Grey appears recessive so therefore both parents must carry that gene to produce it.

If both parents are recessive black, then all resulting puppies will beRecessive Black .  It is hard to know if a Groenendael is recessive black unless this can be determined by relatives or offspring.
