  1. The R26loxp-TAp57k/+;Mlc2v-crek/+genotype is represented in the expected Mendelian ratio in the offspring. However, mice with p57KIP2 cardiac-specific overexpression that are homozygous for the R26p57 allele (R26loxp-TAp57k/k;Mlc2v-crek/+) are significantly under-represented in the offspring (p < 0.01 by Chi-square and n = 203)
