Male chromosome or Y chromosome contains many genes determining various characteristics. It contains less genetic material when compared to X chromosome. Y chromosome also contains unique male genes which are absent on the X chromosome. One such gene is SRY gene in humans. However not all male specific genes are located on the Y chromosome. Some males are born as XXY, and they may show some female physiological characteristics. This disorder is known as Kleinefelter’s syndrome. Some males are born as XYY, and they are known as ‘super’ men usually showing very aggressive male behavior.
Kleinfelter’s carriers are proven able to father children.
Your original post referenced checking the individual's "chromosome count".
The word "count" makes that analysis a quantitative one, while "talk[ing] about the presence of Y chromosomes", as mentioned in your latest post, requires a qualitative analysis.
I am happy to engage in either, but my post was in response to the quantitative nature of your original statement.
