Academics

Problem:

I asked a question related to the third sex, and I came to know that its always possible to categorize a human to male or female with presence of Y chromosome.

Now, I have another question. Is there a way to say if someone has Y chromosome only with external physical test? More specifically:

Question 1: Someone has a penis; can we say that s/he will have Y chromosome?

Question 2: Someone has Y chromosome, can we say that he will have a penis? Please explain.
