It all depends on the combination of genetics and the plants you select.
In general, you can expect that your hybrids will be different than either pure line and express some characteristics from both parents.
female plants that are non-dominant double recessive phenotypical expressions (like an old og kush cutting for example) will be dominated by the male genetics.
If you happen to select a recessive pheno from the male line, the cross could come out much like the parent female.
this also happens when you are breeding with a pure line. Phenotypical expression will be altered based on the traits of the parents you select.
