Pure Gold?Imagine that you have inherited a ranch in California from a distant relative. When you visit the ranch, you instantly fall in love with several magnificent palomino horses. The Palominos are golden in color. They have blonde tails and manes. You decide to breed the palominos. 1. How could you determine experimentally if the palomino color is a hybrid (heterozygous) or a purebred (homozygous) trait?

Suppose that you bred many pairs of palomino horses and they produced these foals: 61 palomino, 32 brown, 29 white.2. Does this observation support the hypothesis that palomino color is purebred? Explain.

3. About what percentage of the foals (baby horses) were a. Palomino?____________________________________b. Brown? ____________________________________c. White? ____________________________________When the foals mature, you breed the brown horses together. All the resulting foals are brown. You also breed the white horse together. All of their foals are white. Represent the genotype of brown horses as BB and white horses as WW. Complete the Punnett square to show the mating of two golden palomino horses.

4. Some people call this incomplete dominance, how would you explain this phenotype?

5. What Genetic phenomenon is demonstrated in this example
