Estimates of regression coefficients ($\beta$) from the bivariate regression of the long-term contributions ($r$) on estimated breeding values ($\text{EBV}$) and estimated Mendelian sampling terms ($\widehat{a}$) for all selected individuals

	Pre-OCS		OCS
	$\beta$ (s.e.)	$F$	$\beta$ (s.e.)	$F$
Males
$\text{EBV}$	10.98 (5.24)	4.38	45.34 (14.37)	9.95
$\widehat{a}$	− 6.97 (9.13)	0.58	9.78 (21.45)	0.21
Females
$\text{EBV}$	0.65 (0.60)	1.18	0.87 (0.51)	2.91
$\widehat{a}$	0.77 (1.25)	0.39	3.21 (0.93)	11.92

Standard errors (s.e.) are between parentheses. The importance of the terms is assessed using F-values; numerator d.f. = 1, and denominator d.f. are 174, 1441, 108 and 1836 for Pre-OCS males and females, and OCS males and females, respectively
