Table 1. Assignment criteria and category definition of white-tailed (WT) and mule deer (MD) hybrids. Heterozygous and homozygous genotype frequencies are required as input prarmeters in NewHybrids to specify the number and configuration of hybrid classes.

		Genotype frequency
NewHybrid category		WT (AA)	H (AB)	MD (BB)	NewHybrid category expanded
WT	Parental WT	1	0	0	WT
MD	Parental MD	0	0	1	MD
F1	First-generation hybrid	0	1	0	(WT x MD)
F2	Second-generation hybrid	0.25	0.5	0.25	((WT x MD) x (WT x MD))
BxWT	First-generation backcross	0.5	0.5	0	(WT x (WT x MD))
BxMD	First-generation backcross	0	0.5	0.5	(MD x MD x WT))
