Queens from one strain, but mated by drones from another strain . Their population and daughters (and drones of them) are F1 crossed. |
| Queen and Drones have the same ancestors: combination to increase or stabilize some characteristics |
| Queen and Drones are Aunt-Nephews : that would correspond by us to a Sister-Brothers crossing. |
| Queen and Drones result of a cross between two different lines : interesting to increase their resistance and qualities. |
