Genetically black and seal are the same "B", but on pointed cats the colour "black" is not really black, it is a very dark brown colour and therefore called seal.
1) Remember that gene B is dominant over all its alleles. For "B-" you might put "BB", "Bb" or "Bb^l". Gene A must be present only once that a cat shows the underlying tabby pattern. For "A-" put "AA" or "Aa". For "D-" put "DD" or "Dd". For "Mc-" put "McMc" or "Mcmc".
2) On the non-tabbypoint colours the genes for the tabby pattern are omitted as they are not relevant for the colour and don't show, but you can put here all combinations of "Mc" and "mc" together with all combinations of "T^a" and "t^a".
3) All tortie are females. Remember that torties must have at least one agouti gene to show a tabby pattern in the non-red areas.

As in most federations only the non-tabby Burmese colours are recognized, the columns for the tabbies are skipped. But genetically tabby Burmese are possible.
You find the sepia (=seal) agouti tabby with A- B- c^bc^b D- f.e. in the Singapura.
A special colour are the silver colours, where Burmese had been crossed with Chinchillas to introduce the silver gene I. The new breed which developed its own standard is called Burmilla, and differs now in type from the Burmese.

non diluted		diluted
brown	aa B- c^bc^b D- oo	blue	aa B- c^bc^b dd oo	1) 2) At the Burmese the colour is called brown or sable, in some federations sepia, because the burmese gene c^b changes the black colour "B" to a brown colour tone.
chocolate	aa b- c^bc^b D- oo	lilac	aa b- c^bc^b dd oo	2) For "b-" You can put "bb" or "bb^l". But note that in the Burmese mostly "bb" is present, even cinnamon Burmese might be possible. The chocolate colour is here a light coffee brown. The lilac colour has a dove grey colour tone.
red	male: aa c^bc^b D- OY female: aa c^bc^b D- OO	cream	male: aa c^bc^b dd OY female: aa c^bc^b dd OO	1)2) Mostly "aa" is present in the current Burmese. We have omitted the combination for "B" as gene O colours all colours to red. You can put here all combinations of "B", "b" and "b^l".
seal tortie	aa B- c^bc^b D- Oo	blue tortie	aa B- c^bc^b dd Oo	1) 2) 3)
chocolate tortie	aa b- c^bc^b D- Oo	lilac tortie	aa b- c^bc^b dd Oo	2) 3) For "b-" put "bb" or "bb^l".
1) Remember that gene B is dominant over all its alleles. For "B-" you might put "BB", "Bb" or "Bb^l".
2) The genes for the tabby pattern are omitted, as they are not relevant for the colour and don't show, but you can put here all combinations of "T^a", "t^a" together with all combinations of "Mc" and "mc".
3) All tortie are females. The tortie colour can be darker as usual on the shorthairs.

Tonkinese

Tonkinese are the result of cross breeding Siamese and Burmese.

Tonkinese

In most federations only the non-tabby and non-orange Tonkinese are recognized, thus the columns for the tabbies, the red and torties are skipped.
But genetically tabby, red and tortie Tonkinese are possible.
You will find the tabby Tonkinese pattern f.e. in the Rex.

non diluted		diluted
natural (=seal) mink	aa B- c^bc^s D- oo	blue mink	aa B- c^bc^s dd oo	1) 2) In the Tonkinese the colours are called "mink" not pointed, may be to show the difference between Siamese pointed and Tonkinese pointed and avoid confusion in naming the various colours.
champagne (=chocolate) mink	aa b- c^bc^s D- oo	platinum mink	aa b- c^bc^s dd oo	2) For "b-" you can put "bb" or "bb^l". But note that in the Tonkinese mostly "bb" is present, even cinnamon Tonkinese might be possible. The chocolate colour is called *champagne. The lilac colour is called platinum*.
1) Remember that gene B is dominant over all its alleles. For "B-" you might put "BB", "Bb" or "Bb^l".
2) The genes for the tabby pattern are omitted, as they are not relevant for the colour and don't show, but you can put here all combinations of "T^a" and "t^a" together with all combinations of "Mc" and "mc".

Tonkinese are not true breeding cats. You can get in a litter all three breeds, the Burmese, the Siamese and the Tonkinese.

Burmilla

Burmilla are the result of cross breeding Burma and Chinchilla.
The Burmilla is a silver shaded/shell agouti cat. If it is silver shaded or silver shell (chinchilla) is the result of careful selective breeding.
In the Burmilla you also might see the Burmese points. You may have in a litter Burmillas and Burmese.

non diluted		diluted
black silver shaded/shell	A- B- c^bc^b D- II oo	blue silver shaded/shell	A- B- c^bc^b dd II oo	1) 2)
chocolate silver shaded/shell	A- b- c^bc^b D- II oo	lilac silver shaded/shell	A- b- c^bc^b dd II oo	2) For "b-" you can put "bb" or "bb^l".
cinnamon silver shaded/shell	A- b^lb^l c^bc^b D- II oo	fawn silver shaded/shell	A- b^lb^l c^bc^b dd II oo	2)
red silver shaded/shell	male: A- c^bc^b D- II OY female: A- c^bc^b D- II OO	cream silver shaded/shell	male: A- c^bc^b dd II OY female: A- c^bc^b dd II OO	1) 2) The combination for "B" are omitted, as gene O colours all colours to red. You can put here all combinations of "B", "b" and "b^l".
black tortie silver shaded/shell	A- B- c^bc^b D- II Oo	blue tortie silver shaded/shell	A- B- c^bc^b dd II Oo	1) 2) 3)
chocolate tortie silver shaded/shell	A- b- c^bc^b D- II Oo	lilac tortie silver shaded/shell	A- b- c^bc^b dd II Oo	2) 3) For "b-" put "bb" or "bb^l".
cinnamon tortie silver shaded/shell	A- b^lb^l c^bc^b D- II Oo	fawn tortie silver shaded/shell	A- b^lb^l c^bc^b dd II Oo	2) 3)
For "A-" put "AA" or "Aa". The Burmillas now are true breeding for silver (gene I).
1) Remember that gene B is dominant over all its alleles. For "B-" you might put "BB", "Bb" or "Bb^l".
2) The genes for the tabby pattern are omitted, as they are not relevant for the colour and don't show, but you can put here all combinations of "T^a" and "t^a" together with all combinations of "Mc" and "mc".
3) All torties are females.
