BASIC COLOUR GENETICS
There are five main sets of genes that will determine how your rabbit appears.
Each parent will pass on one of its set of genes (alleles) to its off-spring. If both are the same it is called (homozygous), for example double agouti 'AA'. If they are different it is called (heterozygous) for example agouti carrying otter 'Aat'.
There is an order of dominance in each set of genes. The colour we see is called a phenotype, the gene sequence we don't see is called the genotype.
Below the most dominant gene is at the top of the list the most recessive at the bottom.

A locus - pattern
'A' will show agouti varieties.
Agouti patterned rabbits are normally banded (banding means that the hair shaft is broken down into segments of colour, this can be described as rings of colour when you blow into the coat).
|
The colours below are examples of agouti banded rabbits. Most agouti rabbits will also have common markings of white bellies, eye cirlcles, under jaw, tail, nose markings. |
However, confusingly, agouti rabbits that are also non extension 'ee', lose the appearance of banding. These agouti non extension rabbits can be distinguished from their self varieties by the presents of a white belly, eye circles, under jaw, nose markings and white inside ears. These colours include: |
Another non banded group includes the jananese brindled varieties (harli and magpie). These however will NOT have the usual agouti markings (white bellies, eye circles etc). |

Another common unbanded colour includes frostie points (all of which are unstandardised). All frostie points must be AA & ee (agouti and non extension). The C locus is variable being either cchd (chin), cchl (sable) or ch (himi) dominant. They can come in BBDD (black), bb (brown/ choc), dd (dilute/blue) and bbdd (lilac) variations.
All sable varieties of agouti are undstandardised.
'at' is the tan pattern.
All tan pattern rabbits have white bellies, white tails, white eye circles and a white jaw and nose (the same as agouti patterned rabbits). The belly will be edged with ticking. However the body of colour is more alike to that of a self rabbit.
The term we use to describe the tan pattern is dependant on what is dominant on the C locus, as the pattern reacts in different ways depending on what it is paired with.
|
C is OTTER- this will include tanning (yellow/ orange) where white markings meet the body of colour.
