Inheritance and Mendelian Genetics
Inheritance means the passing of traits to offspring from parents. These traits could be passed either through asexual reproduction or sexual reproduction. The offspring receives the genetic material from the parents. Mendelian inheritance is a certain b…

Question

Assume that in horses, black coat colour is dominant (B) to chestnut colour (b). The troting gait is due to a dominat allele (T), and the pacing gait is a recessive allele (t)

a) If two Black trotting horses are mated and have for offsprings, all of which are black and pacing, what does that reveal about the probable genotype of the parent horses?

b)A stud is black and trotting. He is mated with a mayor who is also black and trotting. Their colt is black and pacing. The same stud is mated to a second mare who is Chestnut and pacing. Their colt is Chestnut and trotting. What is the probable genotype(s) of the stud, mare 1, colt 1, and colt 2
