4 public questions tagged with this topic.

Which gene is Arabidopsis homolog of Antirrhinum FLO?

Correct option is B, LFY. In ABCE & ABCDE MODEL +Synapdrgon flowering problems like this, the accurate statement is LFY; the others are common mix-ups. Not these: A) AP1; C) AG; D) PI. Tissue transport questions usually turn on xylem vs phloem, living vs dead cells, or source vs sink.

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.

Floral meristem identity genes include:

Pick A: AP1 and LFY. Thinking through ABC MODEL step by step rules out the lookalikes and leaves AP1 and LFY. Skip these: B) AP3 and PI; C) AG and SEP; D) PI and AP2. For hormones and genes, match the molecule or gene to its real role, not a neighboring pathway.
