The examples given above are perfect examples of spun crap..
"wherein as" is totally ungrammatical..it should be simply "whereas" ..( "wherein" exists, as does "whereas" )..but not this redundant association of the two.
"non-purebred" should be in these instances "non pure breed" ( *"non-purebred" does exist, but is incorrect if used in the passages quoted above )
and "pedigreed" quite simply does not exist as a word.
Disagreement with the above corrections, I regret, demonstrates a lack of comprehension of basic English grammar ..not a divergence of opinions ..
Btw ..just in case someone replies with "being as"
( as in "being as my grade teacher told me it is OK etc " )
..it is also a nonsensical association of the two words and is totally incorrect..but many people, and doubtless their English teachers have used it, use it here and elsewhere..as with the other errors, it does not depend on which side of the Atlantic one is.
Spinning makes good or mediocre grammar and text bad, and bad grammar and text appalling..and the semi-literate think that they can write good grammatical prose or that they are able to "correct" spun text.
Disturbingly, the site spell checker here keeps telling me ( by underlining in red )that "write" should be written "rite" .which would obviously be wrong ;-)..either side of the Atlantic.
