CORRIGENDA

In Jefferson, M. C., D. W. Crumpacker and J. S. Williams, 1974 Cold temperature resistance, chromosomal polymorphism and interpopulation heterosis in Drosophila pseudoobscura. Genetics 76: 807–822.

On page 818 in the paragraph headed Interpopulation heterosis for cold resistance, the second sentence should read: "The hetrosis measure of "% F1 over midparent" is that tested by the comparison of "Hybrid vs. mean of parents (P1)" in Table 7."

On page 818 the first two sentences of the discussion should read: "The third chromosome gene arrangements of D. pseudoobscura are associated with different degrees of survival following exposure to cold, both within and between populations. AR and PP confer greater cold resistance then TL and other Misc. gene arrangements on third instar larvae from Boulder, while the reverse occurs for La Foret."
