Joint Probability: Independent Events
Let E designate a dominant allele in horses producing a black coat color and e represent the recessive, such that ee is chestnut. Also, let T represent the dominant allele for Tobiano spotting and t represent the recessive allele for solid coat color, such that tt is solid color.
The genotypic and phenotypic relationships are:
| E_T_ | Black and spotted |
| E_tt | Solid black |
| eeT_ | Chestnut and spotted |
| eett | Solid chestnut |
Fill in the expected probabilities for each of the matings and phenotypes. Answers should be rounded to the nearest thousandth.
