wearing glass to protect from uv rays
The function of muscular system is to move our body, so if I had no muscle in my fingers I wouldn't have been able to type this answer.
For muscle tissue there are three types of tissues: skeletal, cardiac, and smooth muscle. They provide posture and body support, locomotion, and heat production.
Hope you understand what I said

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.
