A2/A2 terminology

[ssimons]

While doing some online looking at various animals, and looking to see how common the A2/A2 characteristic in Dexters seems to be, I came across a term that I don't understand. Thought the experienced folks in the forum might be able to explain the terms.  Here goes; one bull was listed as A2/A2 , and I understand this condition. Each parent contributed an A2 component to the offspring. But another bull was listed as A2N. What are they trying to tell us neophyte Dexter enthusiasts? Any or all explanations of this condition would be very enlightening, at least for me.  Thanks

ssimons,

A2N means A2/A1. :-)

"I was very disappointed to learn that Macree is heterozygous, or "A2N," as the test results say. That means she has one A2 gene and one gene is Negative for A2."

Well Gene , it makes me feel a whole lot better when a long-time dexter rancher like yourself hasn't heard of something I thought I should have known. Especially as frequently I have seen the term used by folks advertising animals for sale, especially bulls. I guess with the relatively new, intense interest in the A2/A2 characteristics we are probably all going to learn a new thing or two in the near future!
    Thanks everyone for all the info. Much appreciated
