Which type of chromosomes determine the sex of an individual?

• A. Homologous Chromosomes
• B. Additional Chromosomes
• C. Sex Chromosomes
• D. Autosomal Chromosomes

Answer: (C)

The type of chromosomes that determine the sex of an individual are the sex chromosomes. In humans and many other organisms, there are typically two types of sex chromosomes: X and Y. Females have two X chromosomes (XX), while males have one X and one Y chromosome (XY). This chromosomal distinction plays a crucial role in determining the sex of the individual during development, and it carries genes that influence sexual development and reproductive functions. Understanding the role of sex chromosomes is fundamental in genetics as they not only determine sex but can also be involved in hereditary conditions and traits that are sex-linked. This is in contrast to homologous chromosomes, which are pairs of chromosomes that have the same genes but may have different alleles, and to autosomal chromosomes, which are non-sex chromosomes that carry genes unrelated to the sex of an individual. Additional chromosomes usually refer to anomalies or variations beyond the standard diploid number that do not play a direct role in determining sex.
