UNC Biology 101 Final questions and
answers 2025 update
temporal isolation - ✔✔ans form of reproductive isolation in which two populations reproduce at
different times
habitat isolation - ✔✔ans Two species encounter each other rarely, or not at all, because they occupy
different habitats preventing mating
behavioral isolation - ✔✔ans Form of reproductive isolation in which two populations have differences
in courtship rituals or other types of behavior that prevent them from interbreeding
mechanical isolation - ✔✔ans Morphological differences can prevent successful mating
gametic isolation - ✔✔ans A prezygotic reproductive barrier where the sperm of one species may not be
able to fertilize the eggs of another species
, prezygotic barriers - ✔✔ans Barriers that impede mating or hinder fertilization.
postzygotic barriers - ✔✔ans barriers that prevent the hybrid zygote from developing into a viable,
fertile adult
reduced hybrid fertility - ✔✔ans Even if hybrids are vigorous, they may be sterile
reduced hybrid viability - ✔✔ans When the genes of different species interact and impair hybrid
development.
hybrid breakdown - ✔✔ans Hybrid is fertile, but when they breed the next generation is sterile.
Node - ✔✔ans A branching point on a cladogram.
Clade - ✔✔ans A group of species that includes an ancestral species and all its descendants.
Taxa - ✔✔ans group or level of organization into which organisms are classified
Hypothesis - ✔✔ans A testable prediction, often implied by a theory
Theory - ✔✔ans A hypothesis that has been tested with a significant amount of data
Law - ✔✔ans Descriptive statement or generalization
Structure and Function - ✔✔ans THEME: each major group of organisms has evolved structures that
make particular functions possible
