Effect of p130 dose on survival of neonatal p107^−/− p27^D51/D51 animals

Basis of calculation	% of mice p130^+/− and:			χ² test P value^b
Basis of calculation	p107^+/−p27^D51/+ and p107^+/−p27^D51/D51	p107^−/−p27^D51/+	p107^−/−p27^D51/D51	χ² test P value^b

The percentage of mice expected with Mendelian inheritance when intercrossing p107^+/− p130^−/− p27^D51/D51 and p107^−/− p130^+/+ p27^D51/+ mice.

The X² test was based on a comparison between the expected and observed percentages of each genotype.
