Reference no: EM1391812

A corn plant is homozygous for a mutant allele that results in no pigment in the seed (ie. white). The mutant is caused by Ds insertion that often exits late in the seed development, when there is an active Ac element in the genome. If there is NO active Ac element the seeds of this plant will be:

A) No pigment (ie white)
B) pigmented all over
C) White with small spots of pigment
D) White with large sports of pigment
E) weakly pigmented
