Here are the main differences in simple words:

- Sex chromosomes help decide if a person will be male or female. In humans these are called X and Y.
- Every person has two sex chromosomes. Most girls have two Xs (XX). Most boys have one X and one Y (XY).
- Sex chromosomes look different from each other. The Y is smaller and has fewer genes than the X.
- Other chromosomes (called autosomes) come in matching pairs that are the same size and carry most of the other body instructions, like hair color or how tall you might be.
- Sex chromosomes can also carry other genes, and sometimes people have different combinations (like XXY), which can change how a body develops.

That’s why sex chromosomes are special compared to the other chromosomes.
