NEET Biology: Reproduction in Organisms questions with solutions

Q1. Drones in a colony of honey bees originate by

1. Thelytoky
2. Arrhenotoky
3. Amphitoky
4. Deuterotoky

Answer: Arrhenotoky

Honey bee drones are males that develop from unfertilized eggs. This mode of reproduction is called arrhenotoky, where unfertilized eggs produce haploid males.

Q2. Which one of the following pairs is wrongly matched while the remaining three are correct?

1. Penicillium - Conidia
2. Water hyacinth - Runner
3. Bryophyllum - Leaf buds
4. Agave - Bulbils

Answer: Water hyacinth - Runner

Water hyacinth does not propagate by runners; it commonly spreads through stolons/offsets and vegetative fragments. The other pairs are correctly matched with their reproductive or vegetative structures.
