Grey, Dun,
Tobiano
Roan, Sabino
And Other Patterns of white

These "colors" are actually patterns of white (grey is progressive) and are not "true" horse colors.  First you must identify the " base" color of the horse.  For example a black and white tobiano would be black.  A grey that was born sorrel, would be sorrel an so on. 

Select the mares "base" color and then calculate that 50% of the foals would also carry the "pattern of white" if the horse is heterozygous (assume this if you do not know for sure) and 100% of the foals would carry the pattern if the mare is homozygous.

Smutty
Pangare'
Sooty
Shade

These effects can change the visual color of the horse (from light sorrel to liver chestnut).  A sorrel horse is genetically the same color as a liver chestnut - but just a different shade.  If a mare is a dark shade, she should pass that darkness onto her offspring at least 50% of the time.

*We are assuming that the mares color has been correctly identified and that she is not homozygous for black or Agouti (black points).
