The number of double transheterozygous embryos that have gaps in the myocardial cell rows is significantly higher than in embryos with only one mutant allele

Genotype (group 1)	# Embryos w/o gap	# Embryos with gap	Genotype (group 2)	# Embryos w/o gap	# Embryos with gap	Genotype (group 3)	# Embryos w/o gap	# Embryos with gap

Chi-square test (χ2), P	χ2=11.99, P1=0.0005			χ2=11.72, P2=0.0006			χ2=13.80, P3=0.0002

The χ² test revealed in all three groups that the proportion of embryos with and without gaps is statistically different for single heterozygous and double transheterozygous embryos. Adjustment for multiple comparisons was performed with the Bonferroni correction (P̃₁=0.0016, P̃₂=0.0019, P̃₃=0.00061).
