You have isolated multiple cells from an individual and analyzed allelic expression of YFG. You find that some cells express the paternal allele, some cells express the maternal allele, and some cells express both alleles. Which type of monoallelic expression is likely? a. genomic imprinting b. randome X-chromosome inactivation c. random autosomal monoallelic expression d. none of the above

20. A corn plant is homozygous for a mutant allele that results in no pigment in the seed (i.e., white). The mutant is caused by Ds insertion that often exits late in 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 (i.e., white) B) pigmented all over C) white with small spots of pigment D) white with large spots of...
