In shorthorn cattle, there are three phenotypes regarding coat color. If they are homozygous they can be red or white. If they are heterozygous they are roan (a color between white and red).

a. What type of dominance is this coat color an example of? Briefly explain.

b. Define letter symbols for each allele and how they combine to give each color. 

What genotypes and phenotypes might be expected from the following matings, and in what proportions? Show Punnett squares or probability calculations as part of your answer when appropriate.

c. red x red 

d. red x white 

e. red x roan 

f. roan x roan
