Ile/Lys polymorphism at amino acid 462 encoded in the 3' end of cpo exon 5.
High-diapause lines, without exception, possess the cpo462Lys allele rather than the cpo462Ile allele.
cpoBG02810/cpo462Ile is associated with higher diapause expression than cpoP3/cpo462Ile.
cpo462Lys/cpoP3 is associated with higher diapause expression than cpo462Ile/cpoP3.
cpo462Lys/cpoBG02810 is associated with higher diapause expression than cpo462Ile/cpoBG02810.
Df(3R)cpo3.42/cpo462Ile is associated with higher diapause expression than Dp(3;3)cpo3.20/cpo462Ile.
cpo462Lys/Df(3R)cpo3.42 is associated with higher diapause expression than cpo462Ile/Df(3R)cpo3.42.
cpo462Lys/Dp(3;3)cpo3.20 is associated with higher diapause expression than cpo462Ile/Dp(3;3)cpo3.20.
