My SO and I are proud breeders of registered Australian Shepherds and today we welcomed 9 puppies…
Now let’s talk genetics. Our female dog (Jitterbug) is a blue merle and the male (Bocephus) is a red tri. Jitterbug is heterozygous for the merle gene (Mm) as one of her parents was a blue merle and the other was a black tri. Since she is heterozygous, she will produce a merle puppy (statistically) 50% of the time. In fact, out of her first litter of 8 puppies, 4 were merles…
Today Jitterbug and Bocephus became the proud parents of 9 SOLID babies. As a math/finance major in college and a current benefits analyst, I did the math… There is a 0.2% chance of a heterozygous merle and a solid having 9 solid babies… Yes I did my research and yes I am confident in my calculations and reserach…
Why couldn’t we defy the odds the other way around with 9 merles??? It’s the same 0.2% chance!
