The up-regulation of protein synthesis and photosynthetic pathways in the AB genome of synthetic polyploid wheat that result in an increase in vigor and restoration of fertility provide good targets for studying the molecular basis of these described phenomena in allopolyploids.
First, women may be more likely to have CDMR when the fertility rate goes down because they believe that c-sections are safer and more beneficial for the baby, and the tremendous importance of having a healthy baby given the low fertility rate provides much of the impetus for having a c-section [40].
