The modern synthesis refers to a. the combination of Mendelian and blending inheritance. b. the combination of modern genetics and Darwinism. c. the combination of modern anthropology with animal behavior. d. the combination of anthropology and biology

B. the combination of modern genetics and Darwinism.

Explanation:

The modern synthesis refers to the concept which combined the theory of inheritance by Mendel and theory of evolution by Charles Darwin. The theory also used the concept of Theory of germplasm.

The modern synthesis concept came in the early 20th century when the studies were going on Mendel's theory and the evolutionary aspects.  The concept led to the formation of new concepts like the macroevolution, microevolution and the evolution affected by mutation of genes.

Thus, Option-B is correct.

The correct answer is  b. the combination of modern genetics and Darwinism.

Explanation:

Modern synthesis is the experimental and theoretical work that was made by combining the work of two scientist Charles darwin and George Mendel. This term was coined in a book called Evolution: The Modern Synthesis.

New definition of evolution was proposed by it which was focused on the genetic basis of evolution for example allele frequency changes in the population. Gene flow, mutation pressure,  natural selection, and random genetic drift were taken as the cause of evolution. So the correct answer is b.

sexual reproduction produces offspring with novel combinations of genes. species that reproduce sexually must maintain two different types of individuals, males and females, which can limit the ability to colonize new habitats as both sexes must be present.
