THE ANCON SHEEP

The shortened legs are a
recessive mutation and do
not give intermediates on
crossing with the long-legged
type, as occurs when a breed
with 'developed' short legs
(such as the Southdown) is
crossed with a long-legged
type.

(From Wriedt, 'Heredity in
Live Stock', London, 1930.)

FIG. 9. CHANGES MADE IN THE
   POLAND-CHINA PIG WHEN
    THE DEMAND FOR LARD
                DECREASED

All the photographs have been
reduced to the same shoulder-height
to show changes in proportions as
distinct from size. The breed has
been changed by selection in the
direction of later maturity, i.e., with
more bone-and muscle-growth and
less fat. These successive changes
are the reverse of the changes which
occur as the pig grows up. This has
been attended with increase in
actual size.

(From Hammond, F. Roy. Agri.
            Soc., 1932, 93.)
