Question regarding Ruderails cream caramel

Ok I have one Ruderails and 3 other regular Sour Diesel going, and was just wondering if the Ruderails can grow seeds if one of the Sour Diesels is a male? or does it just grow buds automatically?

if it gets pollen. you get seeds.

and speaking from a novice growers pov would you grow a male in your garden or take it out and destroy it?
