Question

Drones in a colony of honey bees originate by

• A. Thelytoky
• B. Arrhenotoky
• C. Amphitoky
  
• D. Deuterotoky
  

Answer 1

The correct option is B Arrhenotoky

Parthenogenesis is the method of asexual reproduction in which female gametes develops into the embryo without fertilization.

Based on the sex of offspring, there are following four types of parthenogenesis:

(i) Arrhenotoky - In this type of parthenogenesis, only males are produced by parthenogenesis. It occurs in rotifers, bees (honey bees), wasps, ticks, mites and certain spiders.

(ii) Thelytoky - In this type of parthenogenesis, only females are produced by parthenogenesis. It occurs in Solenobia of Lepidoptera, Lacerta saxicola armeniaca, Ramphotyphlops braminus, etc.

(iii) Amphitoky - In this type, an egg may develop into an individual of any sex (i.e., male or female). It occurs in Aphis (aphid).

(iv) Deuterotoky - In this type, egg develops in both of the sexes (i.e., male and female)

So, the correct answer is option B.
