Question

Natural parthenogenesis is seen in
(a)Housefly
(b)Honey bee
(c)Drosophila
(d)All of the above

Answer 1

Hint: Parthenogenesis occurs in animals with no sex chromosomes. These animals cannot reproduce sexually by the fusion of gametes. In this organism unfertilized eggs normally develop into haploid males.

Complete answer:
In the honeybee unfertilized eggs commonly develop into males with a haploid genome by parthenogenesis. Parthenogenesis is a type of asexual reproduction in which offspring are born without the egg being fertilized by a male. There are a fair number of species of insects, plants, reptiles and fish that can reproduce via parthenogenesis. Some organisms such as crayfish, snakes, komodo dragons, and sharks can reproduce either sexually or by parthenogenesis, this is called facultative parthenogenesis. There are two types of parthenogenesis:
Natural Parthenogenesis: In certain animals, parthenogenesis happens naturally in the life cycles of animals. This is referred to as natural parthenogenesis. Natural parthenogenesis can be complete, where organisms have no males and no sexual phase, or incomplete, where the life cycle of a few organisms involves two generations.
Artificial Parthenogenesis: The fertilized eggs may seldom develop parthenogenetically by different chemical and physical means. This is referred to as artificial parthenogenesis.
Additional information:
Parthenogenesis is essential because of the following reasons:
-Parthenogenesis aids in deciding the sex of an individual in honey bees, wasps, etc.
-It promotes the chromosomal theory of inheritance.
-Genetic variations of populations are reduced by parthenogenesis.
-It is the simplest, and most stable process of reproduction.
-Polyploidy in organisms is created by parthenogenic reproduction.
-It aids in the evolution of advantageous mutant characters.
-There are no sterile races due to parthenogenesis
So, the correct answer is “honey bee”

Note:
 -The fertilized egg in honeybees becomes a female worker. There are numerous workers in the hive. They do all the work of the hive and collect pollen and nectar.
-Among all the bees, there is only one queen in the hive that is fertile. It lays up to 2000 eggs in a day.
