Re: [ASReml] dominance component

Dear Yoonha

I am working with genetic analysis of macadami and am also intersted in
including the dominace relationship matirc in ASReml. A collegue and
mysle fspoke to Arthur about this about a month back and he said he was
happy to do it if someone could put together the rules for forming the
matrix. ITs something I would like to do sometime in the next 6 months
but cant see it happening in the next 3.

Subject: [ASReml] dominance component

I'm working on dominance component in animal model and read chapter 9
'genetic analysis' and chapter 11 'functions of variance components' in
ASReml User Guide (Release 1.0). But I cannot find any content related
to dominant component in animal model.

If anyone have ever worked on creating and using Dominance relationship
matrices, could you give me a simple example?
Or if you have any guide for estimating "dominance component
(variance)", please let me know.

Thank you.

Dear Yoonha,

re: Do you have any guide for estimating "dominant component (variance)"

If you have a good example or any guide for that, please let me know. I
read chapter 9 'genetic analysis' and chapter 11 'functions of variance
components' in ASReml User Guide (Release 1.0), but I cannot find any
content related to dominant component in animal model.

Several people are actively working on creating and using Dominance
relationship matrices but I am not in a position to pass on their work
in progress.

The pronciple is that if you can create the D matrix for your pedigree,
you can read it into ASReml using the GIV matrix mechanism.

You could join the discussion list, and then put your request to the
discussion list.
There may be a user who has done what you want and would be happy to
explain it.

Many thanks
