Abstract
About 40% (alpha = 0.05) of the PCR-derived markers scored in a Medica go truncatula and M. tornata intraspecific cross departed from Mendeli an 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 genot ypes 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 co rrelated with the genome size difference we measured.
