Are close relatives allowed to get married in Australia and Canada?

I think this is allowed. I have seen local people marry their cousins.

Inbreeding just doesn't conform to the principle of eugenics, but it's not as terrible as the legend. I have seen close relatives get married and have three women, each as beautiful as flowers and three graduate students. In fact, it mainly depends on whether there are genetic defects. Inbreeding is only easy to show genetic defects. But if both genes are fine, they should be fine.

Look at this.
