Post by: colleen on Sep 11, 2013
The following coat colors are determined by alleles at one locus in horses:

   palomino = golden coat with lighter mane and tail
   cremello = almost white
   chestnut = brown

The following table gives ratios obtained in matings of the above varieties:

   Cross   Parents   Offspring

   1 cremello X cremello   all cremello
   2 chestnut X chestnut   all chestnut
   3 cremello X chestnut   all palomino
   4 palomino x palomino   1/4 = chestnut
         1/2 = palomino
         1/4 = cremello

Assign gene symbols for the genetic control of coat color on the basis of these data.
Diagram the last two matings.
