Question

What is wrong about bee colonies?
A. Sex determination is based on haplo-diploidy
B. Female dominated society
C. Domesticated species are A. indica and A. mellifera
D. Fertilized egg develops into sterile females only

Answer 1

Hint: A bee colony is a remarkable example of caste division and labor. Every member of the bee colony has got its role and duties which are abided by. Each bee colony consists of a queen bee, hundreds of drones and thousands of work boxes of bees. Queen bees are prolific, fertile and functional females, worker bees are sterile females, and male bees are male insects.

Complete answer:
Option A: This statement is correct as in a bee colony sex determination is based on haplo-diploidy. All diploid individuals are females \[\left( {2n} \right)\] whereas all haploid individuals are males \[\left( n \right)\].
So, this option is incorrect.
Option B: This statement is also correct because a bee colony has many more females as compared to few hundred males. Thus, a bee colony is a female dominated society.
So, this option is incorrect.
Option C: Domesticated species are A. indica and A. mellifera. These two bee species are more commonly used by apiarists or bee keepers for commercial production of honey and its byproducts.
So, this option is incorrect.
Option D: In this option the statement provided is wrong because not all fertilized eggs develop into sterile females whereas one or two fertilized eggs may hatch out into fertile females - the queen based on the nutrition given to the larva.
Thus, Option D is wrong and this option is our answer.

Therefore, Option D. Fertilized eggs develop into sterile females only is the correct answer.

Note:
Bees are flying insects, close relatives of wasps and ants. They occur on all continents of the world except Antarctica. Various bees feed on nectar and pollen. Without bees, pollination would be difficult and time-consuming. Insect pollination is responsible for one-third of human nourishment. Bees have a long straw-like tongue called a proboscis, which allows them to drink nectar from the depths of flowers. Bees also have two wings, two antennae, and three segmented body parts (head, chest, and abdomen). Bees are social insects that live in groups.
