DNA & doubles and divides, making 1 cell have 2 exact sets of nuclei in them.

small, big, or no change could occur in the phenotype. it could cause something as simple as a cats ears to curl backwards or something as frighting as death. it could also occur in the protien-coding area and have an effect on that but no effect on the amino acids. what has to occur is a changing in the hox gene or the control gene.

it is a limiting nutrient limited by a single nutrient in the ecosystem, & the single goes very slow.
