ABC MODEL+PYQS

Loss of function of LFY gene results in:

Correct option is B, Inflorescence instead of flowers. In ABC MODEL problems like this, the accurate statement is Inflorescence instead of flowers; the others are common mix-ups. Not these: A) Extra petals; C) Only carpels; D) Normal flowers. Tissue transport questions usually turn on xylem vs phloem, living vs dead cells, or source vs sink.

Which gene is Arabidopsis homolog of Antirrhinum FLO gene?

LFY (B) is correct here. This is core ABC MODEL: once you know the definition or pathway step, LFY is the clear fit. The wrong ones are A) AP1; C) AG; D) PI. If the topic is about gradients or potentials, water/solutes move from higher to lower of the relevant quantity.

APETALA2 (AP2) is unique because it is:

That points to C: Non-MADS box gene. Compared with the other options, Non-MADS box gene is the one that correctly describes the ABC MODEL concept. The wrong ones are A) Class B gene; B) Class C gene; D) Only expressed in one whorl. If you’re stuck, eliminate anything that contradicts a basic fact you already know for this topic.

Which gene among the following is NOT a MADS-box gene?

That points to D: AP2. Compared with the other options, AP2 is the one that correctly describes the ABC MODEL concept. The wrong ones are A) AP3; B) PI; C) AG. If you’re stuck, eliminate anything that contradicts a basic fact you already know for this topic.
