True

Explanation:

The Modern Synthesis is also called the Neo-Darwinian theory as it explains the fusion of Mendelian genetics with Darwinian evolution into a singular theory of evolution. It is sometimes referred to as the Neo-Darwinian theory.

It refers to evolution as "changes in allele frequencies within populations," in order to explain the genetic basis of evolution. The random genetic drift, gene flow, mutation pressure, and natural selection are seen to cause changes in allele frequencies. Resulting in several differences that can be seen gradually over a particular period in time.

In the Modern Synthesis, mechanisms of evolution and not natural selection takes a major role and it explains the continuance of genetic variation going along with Gregor Mendel's particulate theory of inheritance, where the alleles of a gene remain as individual entities rather than merging.

The major key players of the Modern Synthesis are R. A. Fisher and Sewall Wright (worked on population genetics), Theodosius Dobzhansky (studied the fruitfly Drosophila), Ernst Mayr (models of how speciation occurs), George Gaylord Simpson (introduced paleontological observations into Modern Synthesis) and G. Ledyard Stebbins (added some principles as a result of his botanical studies).
