Evolutionary theory has become the central organizing principle of biological science. Could this scientific theory ever become
sveta [45]

The answer requires looking at the meaning of the words 'theory' and 'law'. The formal definition of a theory is that it is a comprehensive explanation of a observed phenomenon supported by a lot of evidence. Law is a fact that is bound to be true in nature, example Newton's second law. However, a theory is subjected to continuous refinements based on the several new findings that happen with time. These refinements make the theory appear incomplete. As with the theory of evolution, a lot of research work is being put to understand the complex phenomenon of genetic inheritance of traits of behaviour. Unless there are evidences from nature for all the aspects of evolution in theory, it'll remain a theory and not become a law.

Answer is A) Yes, if scientists decide that enough evidence supports the theory.

Cross a plant that is heterozygous for green pods with a plant that has yellow pods
saw5 [17]
G=Green....because your starting plant is heterozygous it must be Gg
g = yellow ....because yellow is recessive, it must be gg

Gg x gg 

Do a Punnet Square and you get
Gg (2)
gg (2)
So half of your plants will be green (but heterozygous) and half will be yellow (homozygous)
