VERNALIZATION & FLOWERING+PYQS

Loss of function mutation in VRN2 results in:

C fits best: Spring varieties that do not need vernalization. Keep the VERNALIZATION & FLOWERING basics straight and Spring varieties that do not need vernalization stands out as the precise answer. Avoid: A) Delayed flowering; B) Requirement of stronger cold; D) Loss of photoperiodism. Light and flowering items often hinge on which photoreceptor or day-length rule is in play.

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.

ABC MODEL+PYQS

Loss of class C gene function leads to absence of:

That points to C: Stamens and carpels. Compared with the other options, Stamens and carpels is the one that correctly describes the ABC MODEL concept. The wrong ones are A) Sepals and petals; B) Petals and stamens; D) Sepals only. If you’re stuck, eliminate anything that contradicts a basic fact you already know for this topic.
