Key Points
Sex chromosomes are the chromosomes that determine the biological sex of an individual. In humans:
- X Chromosome: Females have two X chromosomes (XX), which are responsible for carrying many vital genes, including those related to the development of female characteristics.
- Y Chromosome: Males typically have one X chromosome and one Y chromosome (XY). The Y chromosome contains the SRY gene, which triggers male development.
- The combination of these two types of chromosomes, X and Y, determines the sex of the individual. While "XX" represents the female chromosomal configuration, and "XY" represents the male configuration, the individual chromosomes X and Y are specifically referred to as sex chromosomes.
Hence, the correct answer is XY Chromosomes.
