population All organisms of the same group or species that inhabit the same area and can interbreed genetics The study of how the characteristics of one generation are passed on to the next genetic structure Distribution of genotype frequencies within a population evolution The change in heritable characteristics of a population over generations selection The process whereby a genotype increases or decreases in frequency because it confers a benefit or a detriment to the organism, whi...

BIO 100 EXAM 2 STUDY GUIDE LATEST UPDATE GRADED A+ What characteristic of DNA evidence makes it particularly valuable in criminal investigations? Its uniqueness to each individual organism. What ensures the stability of the complementary base pairs in a DNA molecule? Hydrogen bonds. Why did the double helix model of DNA generate excitement in the scientific community? It elucidated how genetic material could be duplicated through complementary strands. What are the alternative ...
