In which organism males are haploid?
Correct answer: D. Honey bee
- A. Aphids
- B. Mosquito
- C. Butterfly
- D. Honey bee
Explanation
The only organism in the list that has haploid males is the honeybee. This is because honeybees have a unique sex determination system called haplodiploidy. In haplodiploidy, the sex of an offspring is determined by the number of sets of chromosomes that the offspring inherits from its mother. If the offspring inherits a single set of chromosomes from its mother, it will be male. If the offspring inherits two sets of chromosomes from its mother, it will be female.
