The Cream Gene
Reference
Cremello
| DNA Test |
Possible Results |
| Red Factor |
e (meaning ee) |
| Cream Gene |
Cr (meaning CrCr -- double
dilute) |
| Agouti |
A (meaning AA), Aa, or
a (meaning aa) |
Test Results Explained:
With ee (chestnut) mares would
always produce palomino.
AA could not produce smoky
black & smoky cream, but could produce buckskin & perlino
Aa could produce palomino, cremello, buckskin, perlino, smoky black or smoky
cream
aa would pass on the black a gene every time, but not necessarily produce a
smoky black foal as it all depends on which genes the mate contributes.
Cremello could be: ee AA CrCr
or ee Aa CrCr or ee aa CrCr
| Genotype |
Production Possibilities |
|
ee AA CrCr
|
palomino or cremello
only, & buckskin or perlino if mate contributes an E. |
|
ee Aa CrCr
|
palomino, cremello only
& buckskin, perlino, smoky black & smoky cream) if mate contributes an
E. |
|
ee aa CrCr
|
palomino, cremello only,
buckskin, perlino if mate contributes an E and an A, smoky black & smoky
cream if mate contributes an E and it would pass on the little a black
gene every time |

EE could only produce buckskin,
perlino, smoky black, smoky cream & never palomino or cremello
Ee could produce buckskin, perlino, palomino, cremello, smoky black & smoky
cream
EE aa can only produce smoky black or smoky creams unless mate contributes an
A.
aa would pass on the black a gene every time, but not necessarily produce a
smoky black or smoky cream as it all depends on which genes the mate contributes.
Smoky Cream could have Ee aa CrCr or EE aa CrCr
| Genotype |
Production Possibilities |
| Ee aa CrCr |
palomino, cremello, smoky
black, smoky cream & buckskin or perlino if mate contributes an A. |
| EE aa CrCr |
produce no palomino or
cremello, only smoky black & smoky cream, only buckskin & perlino if mate
contributes an A. |
You need a herd of AA mares
