You are a studying the genetic basis of horn color in unicorns. Gene C determines the color of pigment destined for the horn by converting a pink precursor into a purple pigment. C- individuals make purple pigment whereas cc individuals accumulate pink precursor. Gene D ensures the deposition of the pigment into the horn cells, such that D- individuals have a colored horn (purple or pink), whereas dd individuals have a white horn. You breed two purple horned unicorns to each other (CcDd). Assuming Gene C and Gene D are unlinked, what is the probability that the baby unicorn has a purple horn?

Please express your answer to 2 decimal places (e.g. 0.69).
Given data :
- C- individuals make purple pigment
- cc individuals accumulate pink precursor.
- D- individuals have a colored horn (purple or pink),
- dd individuals have a white horn.
Homozygous recessive : when two recessive alleles are present, such as (dd)
Homozygous dominant: when two dominant alleles are present , such as ( DD)
Heterozygous: when two different alleles for a gene are present, for example (Dd).
