Genetic bottleneck - Study guides, Study notes & Summaries

Humans produce sweat as a cooling mechanism to maintain a stable internal temperature. Which of the following best explains how the properties of water contribute to this physiological process? - ANSWER The high heat of vaporization of water allows the body to remove excess heat through a phase change of water from liquid to gas A student placed a semipermeable membrane inside a U-shaped channel with two chambers, as shown. The membrane permits the movement of water but not salt. The...

BIO 107 Study Guide QUESTIONS WITH DETAILED VERIFIED ANSWERS | A+ GRADE ASSURED Microevolution Evolutionary change below the species level; Change in allele frequencies over generations. It is called micro evolution because it focuses on evolution in population, which is the smallest scale. (individuals do not evolve.) 3 mechanisms that cause allele change Natural seletion, genetic drift( chance events that alter allele frequencies), and gene flow (the transfer of alleles between populatio...

Question 1 In conservation genetics, heterozygosity is a fundamental measure of genetic diversity within a population. For example, if a population of leopards has an observed heterozygosity (Ho) of 0.35, this means 35% of individuals possess different alleles at a given genetic locus. In comparison, expected heterozygosity (He) represents the level of genetic variation expected under random mating, and a much higher He value of, for example, 0.52 would indicate potential inbreeding or...
