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

The three types of symbiotic relationships are commensalism, mutualism, and parasitism.
Commensalism: One organism benefits from the symbiotic relationship while the other remains unaffected. Example: Barnacles and whales.
Mutualism: Both organisms benefit in the symbiotic relationship. Example: Humans and the bacteria in their digestive tract.
Parasitism: One organism in the symbiotic relationship benefits at the other organism's expense. Example: Fleas and dogs.
Answer:
Explanation:
Sedimentary rocks are formed via weathering and transport of existing rocks, and then deposition, cementation, and compaction into a sedimentary rock.
