Which of the following statements can be directly inferred from Mendel's Experiment?

The statement that can be directly inferred from Mendel's Experiment is:

"For a recessive trait to be expressed, both copies should be identical."

Mendel's Experiment involved crossing pea plants with different traits and observing their offspring. He found that certain traits appeared in the offspring in specific ratios. He also discovered that the presence of dominant traits masked the expression of recessive traits. This led to his conclusion that for a recessive trait to be expressed, an individual must have two identical copies of the recessive allele. Therefore, the statement "For a recessive trait to be expressed, both copies should be identical" can be directly inferred from Mendel's Experiment. The other statements are not directly related to Mendel's Experiment.
