catahoula pups question

so breeding a merle dog to a black and brindle...if all the pups are merle then that means more than likely the merle parent inherited both color genes as merle...

the other scenario...

if a merle dog is bred to a black and brindle dog and some of the pups are born black and brindle then that means that the merle parent carries 1 merle gene and a black brindle gene which is hidden because it is a recessive...and the reason some of the pups came out black and brindle is because that recessive gene paired up with the black and brindle gene from the non merle parent...when 2 like recessive pair up, one from each parent, then that trait will be displayed...whether it is color or whatever...because we don't know all there is to know about genetics then a good rule of thumb is breed what you see and like...

the more we know about genetics the better choices we can make...
