Subject: in 'Zedonks' what fur characteristic is dominant

If a donkey crosses with a minurature horse it is a given that all of the 
offsprings should be the organism known as "zedonk"  a strong phenotype is the 
fur coat that incorporates stripes and also solid fur colors  i just want to 
know which gene is dominant in the cross?  is it the stripes or the solid 
color?  Is this a case of Co-Dominance?  If so the offspring will have 
phenotypical ratios of 1:2:1 correct?
