Correlations of allele substitution effects for purebred and crossbred performance between Landrace and Yorkshire breeds

Scenario	$r_{\mathit{\alpha }{P}_L,\mathit{\alpha }{P}_Y}$	$r_{\mathit{\alpha }{C}_L,\mathit{\alpha }{C}_Y}$
Nogen	–	–
Gen_AM	0.14 (0.22)	1
Gen_ADM	0.19 (0.24)	0.98 (0.02)

Numbers between brackets are the standard errors of the corresponding parameters

$r_{\mathit{\alpha }{P}_L,\mathit{\alpha }{P}_Y}$ is the correlation of allele substitution effects for purebred performance between the Landrace and Yorkshire breeds; $r_{\mathit{\alpha }{C}_L,\mathit{\alpha }{C}_Y}$ is the correlation of allele substitution effects for crossbred performance between the Landrace and Yorkshire breeds. For Gen_AM, $r_{\mathit{\alpha }{C}_L,\mathit{\alpha }{C}_Y}$ is equal to 1 by definition
