Insects have a variety of sex determination systems, but one common system is known as XX/XO sex determination. In this system, females have two X chromosomes and males have only one X chromosome. The presence or absence of a Y chromosome does not determine sex. Instead, males are defined by the absence of a second sex chromosome, making them XO. Females, as usual, have two X chromosomes.
