Marijuana Genetics

Can someone explain in detail phenotype,hybrid,pure,back crossed,f1,f2 thanks...

just google it, lots of info and to explain it you would have to almost type a book out

phenos -different types of plants from the same pack of seeds,some phenos are like the mom and some the father and maybe a grandpa
hybrid-two none strains crossed
f1-first cross of two strains
f2-inbreeding of F1s
pure-landrace or where it originated
