Breeds & Coat Types
|
| I have listed below some of the more common breeds and coat types of guinea pigs - please feel free to send me a picture of your guinea pig if it is one of the breeds that I havn't illustrated and I'll add it under the appropriate breed / coat type ! |

BREEDS
OF GUINEA PIG

Breed

Piggy !

Features

Genetics
|
|
ABYSSINIAN
This is Rocky |
|
Hair grows in swirls
all over the body, hair neither short nor long (about an inch or so)
|
The
abyssinians are RRmm The rough hair gene RR is dominant over the
smooth hair rr gene of the 'smooth coated' guinea pig..
|
|
ALPACA (Boucle)
This is Missy |
![]() |
Like a peruvian
but with wavy hair like a texel as it has the rex gene.
|
|
|
AMERICAN / ENGLISH SMOOTH COAT
This is Rusty |
Short haired, smooth
and can be of any colour.
|
The
'smooth coat' gene is a recessive rr
|
|
|
CORONET
This is Kiara |
|
The coronet is like
a cross between a sheltie and a crested in that it has long
straight hair but has a crest on the forehead.
|
|
|
CRESTED
This is Robby
Redwood- American Crested Red |
![]() |
English: A 'smooth' haired guinea pig with a flat 'swirl' of hair forming a crest on the forehead. The crest is in the same colour as the coat.
American: The same, however the crest is white in colour. |
The
Star gene St provides the crest on the head.
|
|
HAIRLESS PIGS - There are 2 types of hairless pig:
This is Shirtless |
|
Skinny Pigs - Have a little fuzzy hair on their nose and feet. Baldwins - Have no hair at all ! No picture available at present. |
|
|
MERINO
This is Sebastian |
|
|
The
Merino is llrxrxStSt (A Texel with the Star gene- not sure why
there are 2 St's !)
|
|
PERUVIAN
|
|
Long hair growing
towards the face (like a long haired abyssinian)
|
A
Peruvian is RRmmll (the RRmm from the abysinnian and the ll from
the 'long' hair)
|
|
SHELTIE (Silkie)
This is Simba |
|
Long straight hair
flowing away from the face. Short hair on the face (like a long haired
'smooth' coat).
|
Short
hair is dominant over long hair so long haired guinea pigs are a recessive
ll, the genes of the Sheltie are rrll (smooth - long hair)
|
|
TEDDY / REX
This is also Simba |
|
Short fuzzy hair
! The Teddy and the Rex look the same but have different genetic make
up.
|
Teddy
is tt (kinked hair) and the Rex is rxrx.
|
|
TEXEL
This is Angel Eyes |
|
Long hair in a wavy
pattern, like a cross between a sheltie and a rex but not
as fuzzy as a rex, more wavy !
|
A
Texel is llrxrx (long-hair from sheltie & the rex fuzz)
|
|
COAT
TYPES 'Varieties' of Guinea Pig
|
|
Agouti
Ivan & Moca- American Silver Agoutis |
![]() |
These are most like
the wild cavy's - can be cinnamon, golden, lemon, salmon, silver - they
look like they are flecked or 'ticked' with black (each hair is banded
with colour and black which results in the flecked appearance).
|
The
Agouti coat pattern is a dominant gene symbolised by AA.
|
|
Brindle
|
Black and red hairs,
all mixed together rather than in patches.
|
||
|
Broken
|
No picture available
at present
|
Markings with clean
cut patches of more than one colour
|
|
|
Dalmation
|
No picture available
at present
|
White body with
coloured spots (think dalmatian dog).
|
The
dalmation also carries the Lethal RnRn gene.
|
|
Dutch
This is Trixie |
![]() |
A coloured rump,
and eye patches (of the same colour) resulting in a white midriff and
white stripe down the nose (like a dutch rabbit) white + one other colour.
|
|
|
Himalayan
|
![]() |
White with black
/ sooty / chocolaty 'points' on the tip of the nose, feet and ears.
|
|
|
Marked
|
No picture available
at present
|
Specific colour
patterns on a cavy's coat - usually white with patterns of another colour
|
|
|
Roan Midnight Raven- American Black/Blue roan |
![]() |
Several colours
mixed with white hairs (difficult to describe - like a roan horse!)
|
The
roan gene is RnRn - this is a '*Lethal Recessive' gene.
|
|
Satin
Storm Cloud-American Satin Himalayan |
![]() |
Extremely silky
smooth shiny hair (any colour or length) the hair looks so translucent
as the hair shafts are hollow.
|
The
satin gene is snsn.
|
|
Selfs
Casper the Ghost- American PE White |
![]() |
Guinea pigs all of one colour - Beige, Black, Buff, Chocolate, Cream, Golden [PEG/DEG], Lilac, Red, Saffron, Slate, White [PEW/DEW]. |
|
|
Tortoiseshell
|
No picture available
at present
|
Chequered patches
of red and black.
|
|
![]() |
Chequered patches
of red, black and white.
|
* Thanks so much for pics everyone - more picture credits below ! *
|
* The Lethal
'Roan RnRn' Recessive gene is a genetic
mutation which when Roans are bred to Roans or Dalmations to Dalmation
often results in deformed (malocclusion, blindness) all white, red-eyed
babies that die shortly afer birth. Never breed roans to roans
or dalmations to dalmations.
|
|
Short hair is dominant
over long hair so long haired guinea pigs are a recessive ll, the genes
of the Sheltie are rrll (smooth - long hair)
|
|
Beautiful
Mixtures !
|
Probably the majority of pet guinea pigs are a mix of breeds and don't they look beautiful because of it - such an amazing variety of coats and colours !
|
Here
are a couple of lovely
abby mixes

*Genes:
I have also listed next to each main breed some of the basic genetic
code for each type which helps to illustrate how the breed
came about. I am in no way a genetic expert and just have a very
loose grasp of the basics ! In a nutshell genes carry the 'blueprint'
for every living organism and are attached to chromosomes in a particular
pattern and are passed to the 'piglet' during reproduction from each
of the parents - chromosomes are paired and the piglet receives 1 chromosome
from each parent carrying a particular trait (eg. the rex hair 'style').
Each 'trait' is either dominant or recessive ie. Dominant traits are
more prominent and are symbolised by a 'CAPITAL' letter and recessive
'traits' are symbolised by 'lower' case letters. Each guinea pig takes
on its appearance depending on how these are combined for their coat
type, coat colour (and colour intensity), breed, eye colour etc. Now
that is a very basic outline, I couldn't begin to explain or
understand it all !
