HERITABILITIES OF TRAITS IN ANGUS GROUP TACE

(TRANSTASMAN ANGUS CATTLE EVALUATION).

Only part of the variation that we observe among animals is due to genetic differences. The majority of the
variation is generally due to non-genetic factors such as differences in environment and nutrition. The degree
to which genetic differences influence performance varies from trait to trait. This is explained by differences
in the “heritability” of the traits. Growth and carcase traits tend to have moderate to high heritabilities (i.e.
20 to 60%), whilst maternal traits have low heritabilities (10% or lower). Angus TACE takes into account
the different degrees of heritability of various traits, and the known genetic relationships between the traits.
