You aren’t sure if the genotype of a dog is GG or Gg for golden coat.
In order to determine which it is for breeding purposes, you should
Mate it with a dog that is homozygous recessive
Mate it with a dog that has a grey coat (gg)
Perform a test cross and look at offspring
All of the above

offspring. If purple is
dominant over green,
how many of the 12
offspring would you
expect to be green?
