Answer: Based on the information provided, the most likely answer is: B) Complete Androgen Insensitivity Syndrome
Step-by-step explanation:
1) Congenital Adrenal Hyperplasia (CAH): CAH is a genetic disorder that affects the adrenal glands, leading to abnormal hormone production. This disorder typically results in ambiguous genitalia and can affect sexual development but does not necessarily correlate with a person's gender identity or sexual orientation.
2) Complete Androgen Insensitivity Syndrome (CAIS): CAIS is a genetic condition where an individual with XY chromosomes (typically male) has complete insensitivity to androgens, which are male sex hormones. People with CAIS have external female genitalia, develop as females, and often identify as female. They may have a male appearance but do not have a uterus or ovaries.
3) Turner Syndrome: Turner Syndrome is a genetic disorder that affects females, characterized by the absence or abnormality of one of the X chromosomes. This condition typically results in short stature, infertility, and other physical features, but it does not affect gender identity or sexual orientation.
4) Swyer Syndrome: Swyer Syndrome, also known as XY gonadal dysgenesis, is a genetic condition where individuals with XY chromosomes (typically male) have underdeveloped or absent gonads (ovaries or testes). People with Swyer Syndrome are typically assigned female at birth, have female external genitalia, and may require hormone therapy for development.
Based on the description provided, Amanda having two XX chromosomes and displaying female secondary sexual characteristics suggests that she is not experiencing a genetic disorder. Therefore, the most appropriate answer is B) Complete Androgen Insensitivity Syndrome, as it aligns with Amanda's physical appearance and behavior.
