Which statement about chromosomes and biological sex is correct? Males are XX

Males are XY

Males have XY chromosomes

Explanation:

Males are XY

Explanation:

When looking at the male karyotype, we can see that the last set of chromosomes (the sex chromosomes) is composed of a full-sized chromosome and a smaller, half-sized chromosome. The full-sized chromosome is called an X chromosome and the half-sized chromosome is called a Y chromosome. Males are XY and females are XX. I hope this helps :)
