Some results from crossing experiments of relevance to the New
Zealand sheep industry are examined in relation to the design and
interpretation of experiments aimed at exploring the utilization of
breed resources through crossbreeding. The problems of defining
biological objectives, genetic change between generations,
genetic-environmental interaction, adaptation, and experimental
precision are briefly discussed in relation to the comparisons necessary
for the estimation of genetic parameters of breed utilization.
