In horses, the trotter characteristic is dominant to the pacer characteristic. A male trotter mated with three different females, and each female produces a foal. The first female, a pacer, gives birth to a foal that is a pacer. The second female, also a pacer, gives birth to a foal that is a trotter. The third female, a trotter, gives birth to a fooal that is a pacer. Determine the genotypes of the male, all three females, and the three foals sired.

Please help!! I am so stuck on this!! Thanks!!
 
The male is mixed, so he can give a dominant or recessive to the foal. The mares are recessive, mixed, and mixed. Do your Punnet square for the foals.
 
map it out male trotter mates with three females .1.pacer=pacer
2.pacer=trotter 3.trotter=pacer. The recessive allele is trotter the dominant allele is the pacer, you get more pacers from mating both types of horses. I dont know if this answers your question.
