A species of antelope has 20 chromosomes per set. The species isdivided by a mountain range into two separate populations, whichwe will call the eastern and western population. In a comparison ofthe karyotypes of these two populations, it was discovered that themembers of the eastern population are homozygous for a largeinversion within chromosome 14. How would this inversion affectthe interbreeding between the two populations? Could such aninversion play an important role in speciation?

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.
