    determines an organism's sex and influences other traits

    A sex chromosome, also known as an allosome, is a type of chromosome that determines the sex of an organism. In humans, there are two types of sex chromosomes: X and Y. Females typically have two X chromosomes (XX), while males have one X and one Y chromosome (XY). These chromosomes carry genes that not only influence sexual development but also affect other traits, including some related to hair growth and alopecia.
