To establish whether, using 2 types of markers (allozymes and microsatellites), the growth differential of physiological functions is associated with a genetic basis, and whether this is related to aneuploidy and the identity of missing chromosomes. 5.

Also to estimate aneuploidy transmission to this generation. 6. To evaluate the possibility of selection for a better assimilation efficiency.
