Which type of inheritance does Hypertrichosis fall into?

• A. X-linked
• B. Autosomal dominant
• C. Y-linked
• D. Autosomal recessive

Answer: (C)

Hypertrichosis, commonly referred to as "werewolf syndrome," is characterized by excessive hair growth. It can be inherited through various genetic patterns, but one of the most well-documented forms of hypertrichosis is indeed X-linked. This means the gene responsible for this condition is located on the X chromosome, and it typically affects males more severely than females, as males possess only one X chromosome. The inheritance pattern is significant because the condition can be passed down through families, particularly from carrier mothers to their sons, resulting in varying degrees of expression based on genetic sex. Hence, it is classified as X-linked inheritance. In contrast, options like autosomal dominant or autosomal recessive rely on different chromosomal mechanisms not primarily associated with the patterns observed in hypertrichosis. Therefore, understanding the link to the X chromosome is crucial for comprehending how hypertrichosis can be inherited in humans.
