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?

Expert Solution
Step 1

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).
