Genotype analysis of live offspring from crosses with Bmp2^−/+ mice.

Age	Bmp2^+/+	Bmp2^−/+	Total
(A) Progeny from Bmp2^+/+ × Bmp2^−/+
P21^*	176 (58%)	128 (42%)	304

Age	Bmp2^+/+; Bmp4^+/+	Bmp2^−/+; Bmp4^+/+	Bmp2^+/+; Bmp4^lacZ/+	Bmp2^−/+; Bmp4^lacZ/+	Total
(B) Progeny from Bmp4^lacZ/+ × Bmp2^−/+
P21^*	43 (38%)	38 (34%)	21 (19%)	10 (9%) 112
E12–E18	28 (33%)	19 (22%)	18 (21%)	21 (24%)	86

Age	Bmp2^+/+; Bmp4^S2G/+	Bmp2^+/+; Bmp4^S2G/S2G	Bmp2^−/+; Bmp4^S2G/+	Bmp2^−/+; Bmp4^S2G/S2G	Total
(C) Progeny from Bmp4^S2G/S2G × Bmp2^−/+; Bmp4^S2G/+
P21^*	41 (37%)	37 (33%)	30 (27%)	4 (4%)	112
E12–E18^*	28 (21%)	43 (33%)	50 (38%)	11 (8%)	132
E8.5–E10.5	46 (30%)	40 (26%)	40 (26%)	28 (18%)	154

Data are presented as number (percent). In (A), the expected frequency for each genotype is 50% of total progeny. In (B) and (C), the expected frequency for each genotype is 25% of total progeny.

The observed frequency is significantly different than the expected frequency by Chi-square analysis (P < 0.05).
