What type of sex determination is exemplified by grasshoppers?

Options

  1. AXY type
  2. BXO type
  3. CZW type
  4. DXX type

Correct answer

B. XO type

Step-by-step solution

Due to the involvement of the X-chromosome in the determination of sex, it was designated to be the sex chromosome, and the rest of the chromosomes were named as autosomes. Grasshopper is an example of XO type of sex determination in which the males have only one X-chromosome besides the autosomes, whereas females have a pair of X-chromosomes.
