combined pattern. This holds true as a
general rule for colours which are the re-
sult of a combination of two separate
patterns.
For the grey badgerface colour parti-
cularly, the undercoat fibres on the belly
are thus white, while the outercoat fibres
on the belly remain black. Tlre undercoat
fibres on the upper part of the body will
also be wliite, and so the upper part of
the body will now rnainly produce white
fibres. The badgerface pattern inhibits pig-
ment formation in the outercoat fibres on
the upper part of the body, and the grev
pattern inhibits pigment formation in the
undercoat fibres all over the body.
Colour 11 — grey mouflon (Plates III, 1
and III, 3)
This colour combines the effect of the
mouflon pattern and the effect of the grey
pattern, so that areas that are white in the
black mouflon remain white, while the
grey pattern is manifested only in areas
which are black in the black mouflon.
These are turned grey in the grey mouflon.
In the grey mouflon the white areas usu-
ally show completely white colour, whereas
the same areas are dirty white in the black
nrouflon. The agouti colouring which oc-
curs in black mouflon will also show up
in the grey mouflon, because the grey patt-
ern does not affect the colour of the outer-
coat fibres or the colour of the hair on
head and feet.
Colour 12 — black badgerface-mouflon
(Plates III, 5 and III, 6)
This colour combines the effects of the
badgerface pattern and mouflon pattern in
a similar way to that described under
colours 10 ancl 11, i.e. white areas in eitlier
pattern separately will produce white in
the combination, while black areas must
coincide in both patterns in order to pro-
duce black in the combined pattern.
Thus the head shows a light spot under
the eye from the badgerface pattern ancl
a light spot above the eye from the mou-
flon pattern. The inside of the ears is
light from the mouflon pattern, while the
outside of the ears is light due to the
badgerface pattern. The underside of the
lower jaw and the belly is light due to the
nrouflon pattern, while the outercoat on
the upper part of the body is white due to
the badgerface pattern. The undercoat
fibres on the upper part of the body are
unaffected by both pattern and thus re-
rnain black, giving the base of the staple
a silver grey colour.
On the borderline between side and
belly and on the rear of the hind legs,
there is a darker stripe, where sorne of the
outercoat fibres and all the undercoat
fibres remain black.
Colour 13 — preybroivn badgerface
(Plate II, 6)
This is the same colour as the grey
badgerface, but black pigment is replacecl
by brown. This colour may be very diffi-
cult to distinguish from brown badgerface,
until the lambs are at least 2—3 weeks old.
Colour 14 — greybrown mouflon
This is the same colour as grey mouflon,
with black pigment replaced by brown.
Colour 15 — brown badgerface-mouflon
This is the same colour as black badger-
face-mouflon, with black pigment replaced
by brown.
Colour 16 — grey badgerface-mouflon
In this colour the patterns grey, mou-
flon and black badgerface are superinrpos-
