In horses, black color(B) dominates chestnut color(b). The trotting gait(T) dominates the pacing gait (t). A cross is made between a horse homozygous for black color and the pacing gait and a horse homozygous for chestnut color and the trotting gait.
a.List the probable genotype and phenotype of offspring resulting from such a cross.
b. a cross is made between two horses, both of who are heterozygous black trotter.

_________ ___________ _________ _________
_________ __________ _________ __________
c. Construct a Punnett square and show all the possible gene combinations that results.
d. What is the expected phenotype ration of the offspring?
