2. Interrelationship between score for tan
colour at birth, wool classification
and pelt classification.
Table 2 shows the dassification of wool of
ewes at the Experimental Farm Hestur in
1961 according to their score for tan colour
at birth (Adalsteinsson, 1962).
The difference between score classes w.r.t.
wool classification is highly significant
(x2 6 — 47.79;P<0.001), showing that in-
creased amount of tan colour at birth is re-
flected in increased amount of tan fibres in
the fleeces of adult ewes.
