The leaf color of a certain plant is controlled by one gene. For that gene, the allele G = orange and g = green. You have a plant with orange leaves but do not know whether that plant's genotype is GG or Gg. Which of the following would help you determine the plant's genotype? •cross the plant to another plant with orange leaves

•cross 2 true-breeding, orange-leaved plants to each other and then cross one of their offspring to the plant with the unknown genotype
•cross the plant with green leaves
•change the environment in which the plant grows to find the conditions that cause the leaves to produce the orange color​
