Exam Questions and CORRECT Answers
Speciation - CORRECT ANSWER - The process that produces new and distinct forms of
life.
Species - CORRECT ANSWER - a group of living organisms consisting of similar
individuals capable of exchanging genes or interbreeding. The species is the principal natural
taxonomic unit, ranking below a genus and denoted by a Latin binomial,
Biological species concept - CORRECT ANSWER - Species are groups of actually or
potentially interbreeding populations that are reproductively isolated from other such groups.
Reproductively isolated - CORRECT ANSWER - Members of different species are
incapable of producing offspring
Morphospecies concept - CORRECT ANSWER - Stated simply, the morphospecies
concept holds that members of the same species usually look alike, Members of the same species
usually have similar DNA sequences that are distinct from those of other species.
Ring species - CORRECT ANSWER - species with populations that are reproductively but
not genetically isolated, highlights another shortcoming of the BSC. Here, we find that some
populations within a species are reproductively isolated from each other, but others are not.
Hybridization - CORRECT ANSWER - The act or process of mating organisms of
different varieties or species to create a hybrid
Ecological niche - CORRECT ANSWER - The place or function of a given organism
within its ecosystem. Different organisms may compete for the same niche.
, Ecological species concept - CORRECT ANSWER - The ecological species concept is a
concept of species in which a species is a set of organisms adapted to a particular set of
resources, called a niche, in the environment.
Somatic - CORRECT ANSWER - When mutations occur in body tissue
germline - CORRECT ANSWER - occurring in the reproductive
cells and therefore passed on to the next generation
Gene Pool - CORRECT ANSWER - from all the alleles present in all
individuals in the species
Populations - CORRECT ANSWER - interbreeding groups of
organisms of the same species
living in the same geographical
area
Neutral Mutation - CORRECT ANSWER - A type of mutation that has little to no effect
on organism
Deleterious Mutation - CORRECT ANSWER - a mutation that is harmful or an effect on
an organism
Advantageous Mutation - CORRECT ANSWER - A mutation that causes with a beneficial
effect, they improve their carriers' chances of survival or reproduction
allele frequency - CORRECT ANSWER - The raw information for this comes
from the rates of occurrence of alleles in populations
