Dog Genetics

A Gene series is separated into groups of alleles. Each Dachshund has two alleles from each gene series. One allele inherited from their sire and one allele inherited from their dam. Dominant alleles overpower a recessive allele. Dominant allele will be visible (phenotype) on the puppy. A recessive allele (trait) will be visible only if there are two recessive alleles. A dachshund puppy will "carry" a recessive allele if it is overpowered by a dominant allele.

For an examples on how to do a simple genetic cross go to our genetic cross.

Agouti 'A'

A^ayDominant Red (A^ay A^ay or A^ay A^aw or A^ay A^at ) dominant to all colors.

A^{at at} A^ee Recessive red (clear red ), two recessive alleles are the most dominant tan-pointed color.

A^awWild boar / sable Dominant over all except Red.

A^atTan-pointed colors are recessive to all.

Extension 'E'

Super Extension Mask (Em) is dominant to all other genes in this series. Produces a black mask on the face.

Solid Color (E) the normal color is dominant to Clear Recessive Red and to Brindle. Normal color includes all base coats and can have mixed black hairs within.

Brindle (ebr) the Brindle pattern is dominant to Normal Color and Clear Recessive Red. Brindle can occur in any color and effects tan points with black stripes.

Clear Recessive Red (ee) is the recessive gene of this group. This makes a red color have no black in their coat at all, totally red and usually a light color but can range to very dark. Recessive Red is dominant over the Brown Catagory when having both recessive alleles. Two recessive red alleles (ee) will dominant all tan-pointed colors except recessive red

Brown 'B'

Black ( BB or Bb) is dominant to chocolate. Recessive to Dominant red (ay ) and Clear recessive red ( ee )

Chocolate (bb) is recessive to all colors in the above mention series of alleles.

Albino Dilution 'C'

Full color ( CC or Ccch ) is dominant to Chinchilla dilution.

Chinchilla ( cch ) dilution is recessive to full color, will produce light reds if one allele is present, creams if two alleles are present. No effect on Black but will effect Tan points.

Blue Dilution 'D' Level of Pigmentation

Full color ( Intense pigmentation , DD or Dd ) is dominant to Blue dilution. Blue dilution effects black pigment so a Black and Tan that carries Blue dilution; has 1 dilution allele, may have a liver/bluish colored nose. This can result in very deep rich color such as a mahogany.

Blue dilution ( Light pigmentation , dd ) is recessive, it effects black and chocolate pigment producing blue.

Graying 'G'

Graying (G) Graying takes place steadily over the period of the dogs life.

Non-Graying (gg) Recessive, dog does not gray over time.

Merle 'M'or Dapple 'D'

Dapple (D) Dapple pattern is dominant to having No Dapples. Double Dapple can cause puppies to be blind or deaf.

Non-Dapple (dd) No Dappling is recessive to Dappling

True Sable A^aw - is probably the rarest pattern of all and perhaps the most difficult pattern to describe. Many people mistakenly call a red dog with a heavy black overlay a sable.  This is incorrect; the dog should be registered as red with no pattern.  A true red sable is so dark it almost looks like a black and tan from a distance.  All body hairs, except on the face and feet, are banded with two colors, the self color occurs closest to the dog's body while the darker color occurs near the hair tip.  The face and feet are usually just the dog's self color.  Therefore, a red sable will have body hairs which are red near the base and black near the tips, and a red face and red feet.   One parent must be a sable to produce a sable pup.  As mentioned earlier, wild boar may be the expression of the sable pattern in a wirehaired dachshund.

White Spotting 'S'

Solid (S) is dominant to any type of Piebald pattern; Irish Spotting, Piebald, and Extreme White.

Irish Spotting (i) is incompletely recessive to Solid. This is where you have the required white to be a piebald but no white crosses the back between the neck and withers.

Piebald (p) is incompletely recessive to Solid. Piebald must be more than 50% white. The white is on the neck, chest, all 4 legs, the underbody and tail tip.

Extreme White (e)is incompletely recessive to Solid. The entire body is white except the head.

Ticking 'T'

Ticking (T) is dominant on a pieblad. Ticking is small spots of color in the white portions.

Non-Ticking (tt) is recessive to Ticking pattern on piebalds

Hair Length 'X'

Wirehair X^w Dominant to all.

Smooth X^s Dominant to long hair

Longhair X^l Recessive
