The non-reducing sugar sucrose is most commonly translocated in the phloem rather than reducing sugar. Why?

a.) because they are less reactive than their reducing counterparts

b.) because sucrose contains more energy than a monosaccharides

c.) because the ketone or aldehyde group is reduced to an alcohol or combined with a similar group on another sugar so as not to be oxidized 

Which one of the following statements is true about translocation of non-reducing sugar?

In the pearl-millet plant, color is determined by three alleles at a single locus: Rp1 (red), Rp2 (purple), and rp (green). Red is dominant over purple and green, and purple is dominant over green (Rp1 > Rp2 > rp). What will be expected phenotypes and ratios of offspring produced by the Rp1/rp × Rp2/rp crosses?

B. B blood group baby must be child of Parent A

C. AB blood group baby must be child of Parent A

D. AB blood group baby must be child of Parent C
