<span>Aphotic zone (bathypelagic zone)</span><span> The region of a lake or sea where no light penetrates; it is situated beneath the </span>euphotic zone<span>. The aphotic zone contains no algae or phytoplankton, and its inhabitants are exclusively carnivorous animals or organisms that feed on sediment or detritus, all reliant on energy inputs from the euphotic zone.

Answer:
Phenotype ratio= 12 colorless : 3 purple : 1 red
Genotype ratio= 1:2:1:2:4:2:1:2:1
Explanation:
According to the given information, the dominant allele "I" is epistatic to P and p alleles and presence of "I" inhibits the expression of both "P" and "p" alleles.
A cross between two heterozygous plants for both locus would give the F2 progeny in 12 colorless: 3 purple: 1 red ratio.
Here, the F2 genotype with "I-G" and "I-gg" would produce colorless kernels while the ones with "ii-G-" would exhibit purple colored kernels. The F2 genotype "iigg" would beak red kernels.
Hence, the phenotype ratio= 12 colorless : 3 purple : 1 red
Genotype ratio would be same as for the mendelian dihybrid cross= 1 IIPP: 2 IIPp :1 IIpp: 2 IiPP :4 IiPp: 2 Iipp: 1 iiPP :2 iiPp: 1 iipp
