It certainly is not at all difficult to understand, and it's fun for those of us that love genetics, but anyone who DOES NOT, WILL NOT, or CANNOT understand and continues to breed, IS, at a minimum, either ignorantly (if they never knew) or stupidly (if they knew and ignored and/or did not pursue their education) "asking for trouble"...and they may "get lucky" for a time but they WILL eventually find that TROUBLE (double recessives, such as blue born Yorkies)
will happen because the genetic programming exists.
A certain Westminister Winner (collie) and his non-show-able deaf and blind double merle (a doubled recessive gene) daddy comes to mind...and
the breeders supposedly KNEW what they were doing and purposely bred for the double merle:

It is truly great that you joined YT, but this is a "forum" where members share information and experiences, help each other, and learn from each other, as I understand YT and forums in general. Yes, there is a lot that you can learn in a forum...YT included, of course, since there are some highly knowledgeable members, breeders, etc., here...and I do not even include myself in that statement.
But, and with no offense intended
, YT should NOT be your educational basis for your breeding program.
I created three (3) simple Punnett Squares to demonstrate the genetic permutations that are possible with recessive carriers and double recessives using "G" to represent "Any Dominant Gene" and "g" to represent "Any Recessive Gene" in my charts...to show how your dilute carrier, Sasha, and the dilute carrier sire of her last litter, created the double recessive dilute "blue born" puppy, "Blue Ivy" from a visual standpoint...but if you
really want to understand, you should not only get breeder/vet/etc. mentors willing to apprentice you and read/research in books, etc...you should also take some educational courses in genetics, animal husbandry, etc., as well,
since you started your breeding program WITHOUT knowledge of genetic possibilities.
I say this
only as a suggestion and
only because...now that you have been breeding without proper knowledge, you may now need to 'unlearn' possible bad practices that no mentor will KNOW you possess that could harm your future "professional breeder" reputation, your lines, your breeding stock, and your pups...so they may not cover that information with you and you may/will not know about it to ask. A mentor who 'knows' you have already been breeding may 'assume' you have the basic knowledge required and skip over it. Educational courses automatically 'assume' you know nothing at the start of the course and teach you anyway, even if you already do have all/most/some of the knowledge. "We do not know what we do not know."
Again, I would like to re-iterate...I am NOT a breeder, not a vet, not a geneticist, not anything anywhere near like that.
I have had pregnant females (canine and feline) welp under my care, but at no time have I set out to breed animals professionally. I am also not a medical professional and am not offering professional advice of any sort...only personal opinion and suggestions. My only involvement in your situation is due to my personal genetics interest, apptitude, research, and past experiences...not ambition or profession.
I hope you will not find my comments insulting or offending in any way. I do wish you the best of luck in your endeavor as you separate your past breeding habits while acquiring advanced breeding knowledge, and the best of luck in caring for Blue Ivy.
