Dear Fislik,

There are two issues in the job.

 test 6 !I # number of locations
 rep !I # blocks are nested within locations
 female !I
 male !I
c:\research\tip\mw\ind_2.csv !SKIP 1 !DOPART 1

height ~ mu test rep.test !r,
male and(female) test.male and(female) male.female test.male.female
predict male

First, for 'male and(female)' to correctly overlay the male design
matrix with the
female design matrix, the columns MUST correspond which means that the
ith 'male'
must be the same individual as the ith 'female'

female !I male !I

is most unlikely to achieve this (unless the initial N lines in the data
file referred to the selfing
of all N individuals)

Assuming N was 30 (26 appearing as males and 22 appearing as females)
female 20 male 20
would achieve the desired effect if the individuals are comformaby coded 1
... 30 in these feilds of data file

Otherwise, create a 'pedigree file' which lists the (30) individuals

40245 0 0
52645 0 0

and then use

 female !P male !P

so they are coded comformably.

Issue 2:
The second line of the model will need to be written

male and(female),
 test.male -test.female and(test.female),
   male.female test.male.female

if I understand your intention.

Grace, mercy and peace to you from God our Saviour Jesus Christ
