So here is my puzzler for you

Porter is a native

Porter's sire =imperial and both of his sires parent's = imperial

Porter's Dame = native and both her parent's = native

HOW or WHY is Porter a native if imperial is supposed to be dominate

If Imperial is dominant, they can have either 2 Imperial genes (I,I) or one of each (I,n). So 2 parents with (I, n) can each give their n gene to the calf, and the calf will be native (25% chance).

I thought Native was dominant... more common isn't it? If native is dominant, then the info about the parents is incorrect.

peeing is good. keep drinking

Oh and here's the kicker Porter's grandfather was imperial BUT out of 2 native yaks NOT supposed to happen from what I have read

It could happen if the native condition is dominant, which is what I am thinking.

Color Inheritance
Imperials are either homozygous Imperial or heterozygous Imperial.
Only one copy of the Imperial gene is required for the Imperial gene to dominate over the Native Black or Gold colors and produce Imperials. A homozygous Imperial bull will always produce Imperial offspring when bred to Native Black females. When bred to Royal females he will always produce Imperial Trims. A heterozygous Imperial bull will produce a mixture of Imperial and Native Black offspring when bred in the same manner.

what a day Wishing ! Did any of the pics. turn out ?

Hi mare, Is your sister gone now ?

It was another day of driving!! Yes, some good pics. I'll get the phone in a bit and post some.

If that info came from that original paper written for the IYAK website, I think the info is questionable. The author was obviously using his own experience and observations, but there may be more to the genes than simple dominant/recessive. Take human eye color. Brown and blue are simple dominant/recessive with blue being recessive. 2 blue eyed parents cannot have a brown eyed child. Period. But take hazel, green, or grey eyes. Not a simple case of dominance. There are something like 8 different genes that contribute to the hazel color. No one really knew the how the genes interacted to create the color until the DNA was sequenced. There is still a lot they don't know about hazel.

So with the Yak genes, either there are more complex interactions going on (more than one pair of genes determining nose color) OR the info/record keeping is incorrect. One of the universities is sequencing the yak genome, so you may have to wait until they know for sure what is really going on.

If the gene pair for Imperial is truly a case of simple dominant-recessive, the offspring nose color is predictable based on percentages and there would be no way for 3 2 native yaks to produce an Imperial calf. First word of the sentience is most important... IF


edit: impossible for 3 native yaks to produce offspring, but for different reasons!

Does that factor in my brown eyes turning hazel ? LOL

Hubs and the boys were in Kalispell summer before last to go to Glacier National Park. They saw lots of Bighorn sheep, but no yaks, sadly.

Did you read my edit in the last post?

I just chalk that up to you being a unique/special individual
