Let me preface this with I'm not fond of stereotypes, but are the "typical" male traits (see details) learned or genetic?

I had this discussion with another jelly earlier this week. Let’s face it, there are some male behavior patterns that are pretty “typical” of men. No concern about clutter, clothes that don’t make it to the hamper, enjoyment of body functions, etc. It’s not always men that exhibit these, but it’s pretty common across our group. What really made me wonder about this happened at Thanksgiving. My nephew put his face against my chest and ripped off a huge belch. Then he looked at me with this huge grin, like look what I just did. He’s not even 9 months old. My apology in advance to Simone. But I’m curious what everyone else sees.
