Final answer:
Individuals with the most common form of androgen insensitivity syndrome have the sex chromosomes XY and are genetically male. However, due to a lack of response to male sex hormones, they typically develop external female genitalia and are raised as females.
Step-by-step explanation:
Individuals with the most common form of androgen insensitivity syndrome have the sex chromosomes XY. Androgen insensitivity syndrome (AIS) occurs when an individual with XY chromosomes does not respond properly to male sex hormones. This leads to the development of external female genitalia and the absence or underdevelopment of internal female reproductive organs. Although genetically male, these individuals are typically raised as females.
