Sable bred Buff

AN EXPLANATION OF SABLE BRED TO BUFF COLOR INHERITANCE

There seems to be some confusion about whether sable is recessive to buff. This is an attempt to clarify this. There may be the appearance of repetition but each gene combination needs to be examined by itself. It is assumed that the reader has a basic understanding of MENDEL'S LAW and has a working knowledge of coat color inheritance as published by C, Little ( who's work has proven to be 100% accurate (except for his assumptions about roan grading in to ticking ) at least as far cocker spaniels are concerned . " what else counts" ) The buff gene and the sable gene are inherited independently of each other but because of the similarities in appearance are easily confused.

The buff gene is located at the 'e' locus and comes in two (2) forms'E' (non buff) and 'e' (buff). 'E' (non buff) is dominant to 'e '(buff) recessive.

The sable gene is one of a trio ( 3 ) and is located at the 'A' locus.They are 'A' (solid) (non sable) (non tan points) dominant,'ay' (sable) recessive to 'A' (solid) but dominant to 'at' (tan pointed), and 'at' (tan pointed) recessive to 'A' (solid) and 'ay' (sable).The sable gene is in reality another of the dilution effects similar to buff so often seen on cockers.

The sable gene is commonly considered dominant to tan points but in its hetrozygous expression is in reality
what would would be called co-dominant . The reason for this is that the typical sable ( A hetrozygote of 'at-ay' ) yellow
with dark overlay

) is actually half way between tan points (

'at-at') and true sable(

'ay-ay'(clear yellow looks the same as buff ).

For simplicity it is assumed that these hypothetical cockers have at least one gene for black "B"

1. If you breed a buff 'ee' carrying 'AA' (solid) to a sable assuming it is the typical sable, 'ay at' (a yellow dog with black overlay) carrying 'EE' (non buff) you could expect to get all black
puppies.chart 1sbb

2. If you breed a buff ('ee') carrying 'A' (solid) 'ay' (sable) to a typical sable '(at ay') carrying 'EE' (nonbuff) you could expect to get
50% black
25% typical sable
25% true sable (clear) (ay ay looks like buff) chart 2sbb

3. If you breed a buff ('ee') carrying 'ay' (sable) 'ay' (sable) to a typical sable ('ay at') carrying 'EE' (non buff)

7. If you breed a buff ('ee') carrying 'A (solid) 'A' (solid) to a typical sable ('ay at') carrying 'e' (buff) 'e' (buff) this dog
would, also, be buff so 100% of the puppies would be buff.
