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.
Was a major source...past tense ? don't go by this answer I'd say plants..not sure how specific...lmk and ill answer it if you're still on this
The answer to this is Heat because it helps the rock molten and vicious.
Answer:
Carley has become operantly conditioned.
Explanation:
Operant conditioning can be described as a method of learning which focuses on the rewards or punishments that will be given in course for an action. As Carley has learned that whenever she wants a rush of natural adrenaline, she needs to swim forty laps in the pool, she considers it to be a reward. Such type of practices behaviour demonstrates operant conditioning.
