What is the recessive trait in pea plants?

• The trait is expressed when at least one dominant allele is present (Hh)

• The trait is expressed only when two recessive alleles are present (hh)

• The trait is always expressed regardless of the alleles present (HH)

• The trait is expressed when one dominant and one recessive allele are present (Hh)
