Could Ronda Rousey defeat Floyd Mayweather Jr. in a fight?

A couple of weeks ago, while promoting the Ronda Rousey-Cat Zingano fight, UFC President Dana White said he is running out of opponents for her and jokingly said that maybe he should have her start fighting men.

Everyone laughed, then a few days later, Rousey went out and defeated Zingano in 14 seconds. Suddenly, and old debate began again: Could Rousey defeat someone like Floyd Mayweather Jr.?

Some say no way, some say yes, and some say it depends on the rules of the fight. If it was held under MMA rules, Rousey would win; if it was held under boxing rules, Mayweather would win.
