Homework Answers
d. You are growing a corn plant that is homozygous for a mutant allele that results in no pigment in the seed (ie white). The mutant is caused by a Ds insertion that often exists late in seed development , when there is a active Ac element in the genome. If there is not a active Ac element in this plant , the seed of this plant will be white with large spot of pigment.

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...

1) Given a plant with the genotype C/cm; Ac+/Act, where om is an unstable allele caused by a Ds insertion. This plant is crossed with another plant with the genotype C/cm where cm is an unstable allele caused by Ac insertion. What phenotypes would be produced (including their proportion)? Assume that Ac and c are unlinked, that the chromosome-breakage frequency is negligible, and that mutant c/C is Ac+. 2) Is it possible for non-dividing neuronal cells to employ the homologous...

A mutant plant with white flowers exists that lacks red anthocyanin pigment, normally made by enzyme P. Indeed the petal tissue lacks all detectable activity for enzyme P. Despite the lack of enzyme activity, a study of homozygous mutant cells using antibodies against the wild-type enzyme demonstrated that the cells homozygous for the mutation still had the enzyme (i.e., the antibody showed the presence of the enzyme). Which statement below could most likely explain these results? A )The mutant had...

2. A dominant allele H reduces the number of body bristles that Drosophila flies have, giving rise to a “hairless” phenotype. In the homozygous condition, H is lethal. An independently assorting dominant allele S has no effect on bristle number except in the presence of H, in which case a single dose of S suppresses the hairless phenotype, thus restoring the "hairy" phenotype. However, S also is lethal in the homozygous (S/S) condition. What ratio of hairy to hairless flies...
