Answer:
Genotype
Step-by-step explanation:
Given:
The final form that a plant attains will be determined by both its genetic heritage (genotype) and the environment. (An organism's capacity for responding to environmental change within a single genotype is called phenotypic plasticity.) However, one or the other factor can dominate during the development of some features.
Solution:
Genotype influences the leaf tooth traits in Acer rubrum trees.
Genotype indicates the hereditary potentials as well as the limitations of an individual from the stage of embryonic formation to the stage of adulthood.
