Normal human cells have two types of chromosomes, which have nothing to do with sex determination.

There are 23 pairs of chromosomes in each cell of human body. Includes 22 pairs of autosomes and one pair of sex chromosomes. Sex chromosomes include: X chromosome and Y chromosome.

There are major sex-determining genes on sex chromosomes, but not on autosomes.

To sum up, chromosomes in normal human cells are autosomes that have nothing to do with sex determination.

Hope to solve the landlord's doubts!
