Genetic Evolution

Sexual reproduction produces distinct population variations. Heredity determines the traits and qualities to be passed down to the progeny. Over time, this variation within-species is also affected by the process of human evolution. The study of how genetic variation leads to evolutionary changes is known as genetic evolution. If a trait helps an organism to survive and reproduce, it is more likely to be passed down the generations. It is rare that such traits result in a completely distinct set of traits in descendants than the ancestral population; this can result in the emergence of a new species.

Question

Which term can most accurately be used to describe evolutionary change that leads to speciation?

A. microevolution

b. macroevolution

c. sexual selection

d. natural selection

e. reproductive isolation

Definition Definition Process by which new species arise. This occurs when populations of a species become isolated and diverge, developing unique traits through natural selection, genetic drift, or other mechanisms. Over time, these differences accumulate until the populations can no longer interbreed and are considered separate species.

Expert Solution

Step 1

Introduction :-

Reproductive isolation refers to the phenomenon in which populations of the same species become unable to interbreed and produce fertile offspring. This can occur due to various factors such as geographical separation, behavioral differences, or physiological differences.
