摘要：
About 40% (alpha = 0.05) of the PCR-derived markers scored in a Medicago truncatula and M. tornata intraspecific cross departed from Mendelian expectations at alpha = 0.05. This proportion is among the highest ever documented in the literature, notably for intraspecific crosses. Estimations of DNA amount were also implemented for the parental genotypes or parental lines, and significant variations were observed. Our results suggest that the parental genotypes have diverged for quite a while, and we propose that the level of distortion we documented is correlated with the genome size difference we measured.
