Answer the following questions and show how you obtained the answer as simply as possible because I do not understand

2. Horses can be Cremello (light cream color). Chestnut (a brownish color) or Palomino (a golden color with white in tail and mane). Of these phenotypes, only the palominos never breed true. A Palomino by Palomino cross yields the follow offspring: 100 Chestnut, 200 Palomino, 100 Cremello horses. A Palomino by Cremello cross yields 1/2 Palomino and 1/2 Cremello offsprings How many genes control coat color in the horse? Give the mode of inheritance. Why do Palominos not breed true? a. b. c. Bonus (5 points): 1. Choose one of the questions you did not answer and complete that question as your bonus question. You must clearly mark your bonus question with the word "Bonus" and place it at the end of your compulsory questions, as the point value differs from the regular questions

Explanation / Answer

Ans 12 :

a) Since there are a total of three phenotypes , out of which one cannot breed pure , indicating that its genotype is heterzygous. So there are a total of three genotypes , and the number of genes controlling the coat color in horses are two.

b) The mode of inheritance is incomplete dominance.

c) The palminos do not breed true , because as the genes are true , the palmino's genotype must be heterozygous.
