Cross pollination query

From a fellow grower: During the growth stage of the feminized seeds I purchased from you if they are accidentally crossed pollinated from a nearby non hybrid male plant of a standard bush strain what will happen to the buds of the feminized kush plants?
1)- Will they produce seeds?
2)- If so will the seeds be fertile, ie (able to grow flowering productive plants), or will the seeds produced be useless (sterile), or will they produce mainly hermaphrodite plants?

if the bush plant was male

Fertile-yes, sex to be determined since it will result in a regular seed.

If both female plants

Fertile yes, sex female

Iā€™m not sure of Hermaphrodite chance
