You are studying two genetic loci that are on the same chromosome. One of the loci is a gene that produces darker feathers in dark environments in birds. The second locus is a gene associated with metabolism. In your research you find that the second locus is not under selection, but the first locus is undergoing positive selection. The positive selection at the first locus is increasing a specific allele at the second locus. This discovery of yours is best described as which of the following?   a. Recombinaton   b. Linkage equilibrium   c. Genetic hitchhiking   d. Chromosome inversion

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.
