Histone deacetylation will cause chromatin to be more open and therefore not inhibit expression of genes in that region.

Which statement best describes the meaning of a p value in a chi-square analysis?

The longer one lives the more epigenetic marks will accumulate based on diet and environment.

In plants, chlorophyll production (W_ , green) is completely dominant to non-chlorophyll production (ww, white) and ww is lethal about two weeks after germination.  What will be the phenotypic ratio in the offspring of two heterozygous plants after two months has passed?

Coat color in rabbits is inherited as a series of four multiple alleles (C+ agouti > cch  chinchilla  > ch  Himalayan > ca albino).  What F1 phenotypic ratio would result from a cross between a pure breeding agouti and a pure breeding albino?

The equation represents ___.
