Need some help PLEASE

Had a friend give me some seeds which supposedly cam from pretty good weed. My question is can you tell a good seed verse a bad seed (quality) by looking at the seed? Is a dark seeds better than light is stripes better than none ect...... Thanks for your help

Normally the seeds with stripes are the best...but i have had some fucked up looking egg shaped seeds sprout on me...its all in genetics bro, but typically dark striped seeds are the best ones and you cant tell till you germ. them unfortunately. There are many methods that people say work....I just germinate them to find out
