If you have questions with breeding---I can help. To answer your question you will have to breed both strains ( A-fem x B-male) then (B-fem x A-male). Each individual strain(male and female) will have dominate and recessive traits compaired to the strain you cross it with. My suggestion would be to start with strain you want to come through the most as your fem first----------what about when to use the male of one and the female of the other..???
does the male carry the dominant genes? as for crossing 2 strains mainly..
