The correct option is C XO type of sex chromosomes determine male sex in grasshopper
A sex-determination system is a biological system that determines the development of sexual characteristics in an organism. Most organisms that create their offspring using sexual reproduction have two sexes.
There are five main genetic mechanisms of sex determination
- XX-XY method: XX - female, XY - male, eg, mammals, some insects like Drosophila.
- XX-XO method: XX - female, XO - male, eg, roundworm, grasshoppers, insects.
- ZZ-ZW method: ZW - female, ZZ - male, eg, birds, reptiles, fishes.
- ZZ-ZO method: ZO - female, ZZ - male, eg, moths, butterfly.
- Haploid-diploid method: An unfertilized egg develops into a male and a fertilized egg develops into a female, eg, honey bees.
