Difference in proliferative capacity in reciprocal male and female F1 hybrid mice.

Cell proliferation (A) and CFC generation (B) per 50 input Lin⁻Sca1⁺⁺kit⁺ cells isolated from male and female D2B6F1 and B6D2F1 hybrid mice. Results are given as mean ± SEM. P values indicated on the figure were obtained by paired t test (n = 4 for female D2B6F1 and B6D2F1 mice; n = 8 for male D2B6F1 and B6D2F1 mice).
