Can someone make a pedigree chart for this?

the dna molecules have a negative charge because of the phosphate groups in their sugar-phosphate backbone, so they start moving through the matrix of the gel towards the positive pole. power is turned on and dna fragments migrate through gel (towards the positive electrode).

explanation:

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