To design a test to determine if the ebony color is dominant over yellow, you would need to perform a series of breeding experiments and observe the offspring’s coat color. Here is a step-by-step approach to designing such a test:

  1. Select Parental Generation: Choose two purebred individuals with known coat colors - one ebony and one yellow. These individuals should have no genetic variations in their coat color genes.

  2. Cross the Parents: Mate the ebony individual with the yellow individual. Ensure that the mating results in a large number of offspring to obtain statistically significant results.

  3. Analyze F1 Generation: Observe the coat colors of all the offspring from the cross. If the ebony color is dominant over yellow, you would expect all the F1 generation offspring to have ebony color.

  4. Perform F1 Cross: Take two F1 offspring with ebony color and mate them with each other. This is called an F1 cross or a test cross.

  5. Analyze F2 Generation: Observe the coat colors of the offspring produced from the F1 cross. Count the number of individuals with ebony color and the number of individuals with yellow color. If ebony is dominant over yellow, you would expect to see a higher proportion of ebony offspring than yellow offspring.

  6. Perform Statistical Analysis: Use appropriate statistical tests to determine if the observed results are significantly different from what would be expected by chance. This analysis will provide evidence for whether ebony color is indeed dominant over yellow.

  7. Repeat the Experiment: For more accuracy and reliability, repeat the test several times with different sets of individuals to ensure consistent results.

By following this breeding experiment and analyzing the coat colors of the offspring, you can determine if ebony color is dominant over yellow. Remember that the results may vary depending on the specific genes and alleles involved in coat color inheritance in the particular organism under study.
