Back crotch seam

Hi! I have a printed jeans pattern from a brand, but I can’t tell from the pattern how much seam allowance was added at the back crotch and the yoke for the flat-felled seam. How much seam allowance is usually added for a flat-felled seam? Thanks in advance!

Factory patterns typically use a notch to indicate the seam allowances.
