Five different genes are known to specify floral organ identity in Arabidopsis: APETALA1 (AP1), APETALA2 (AP2), APETALA3 (AP3), PISTILLATA (PI), and AGAMOUS (AG).

Which one of the following statement is incorrect?

#Unit 5. Developmental Biology
  1. plants with the ap2 mutation lack sepals and petals
  2. Plants bearing ap3 or pi mutations produce sepals instead of petals, and carpels instead of stamens.
  3. plants homozygous for the ag mutation lack both stamens and carpels.
  4. Plants bearing ap3 or pi mutations produce petals instead of sepals, and stamens instead of carpels.
