b) parasympathetic- acts in normal life conditions

Answer:
The modern evolutionary synthesis defines evolution as the change over time in this genetic variation. The frequency of one particular allele will become more or less prevalent relative to other forms of that gene.
Explanation:
A substantial part of the phenotypic variation in a population is caused by genotypic variation.
