The first electrons to be excited by light energy are found in Photosystem II (PSII). It is a specialized protein complex that captures the energy from sunlight and uses it to extract electrons from water molecules.Light is absorbed by chlorophyll, carotenoid and phycobilin pigments in the antenna regions. The excitation energy is rapidly transferred to the reaction centre domain.

Dmitry_Shevchenko [17]
A renewable resource is something that provides power but will never run out. Eventually natural gas and oil and coal will run out. Wind is renewable because it will never run out, unless the world ends, then it won't matter.

A mutation that causes a yellowing of leaves in snapdragon plants was discovered in the early 1900s. Plants with this condition,
Serga [27]
Looking at the second cross, a 2:1 phenotypic ratio (instead of the typical 3:1) usually indicate a lethal homozygous genotype. Based on the question, it’s sensible to assume that a snapdragon homozygous for the aureal allele, which should have a even lesser chlorophyll count than the heterozygote, can’t even make it to the birth of the plant, thus the GAGA type never existed in reality. Under this assumption, we can deduce that the 2/3 aurea is of genotype GAG and the 1/3 green offspring of genotype GG. If a punnet square was pulled including the lethal genotype, it will be easily seen that the aureal allele is the dominant type. The first cross of genotype GG x GG conform to this conclusion. And the third is therefore a test cross between the homozygous recessive GG and the heterozygous GAG (aurea), with the result abiding our theory. Correct me if I was wrong, the GA allele is termed dominant negative as a single copy of it results in a deficit in chlorophyll amount. But anyway, the explanation above should give you an answer to the relationship between the G and GA allele.
