Question

Which statement about chromosomes and biological sex is correct?

Males are XX

Females are XY

Males are XY

Answer 1

Males are XY

Step-by-step 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 :)
