The combination of alleles that an individual posesses.
These are preserved specimens found in sedimentary rock
A permanent, random change in DNA that introduces new genetic variations.
What is Mutation?
Two populations of the same species may eventually become two separate species if they experience this.
What is reproductive isolation?
Bacteria create offspring via this type of reproduction.
What is asexual?
DNA contains the instructions for building these molecules.
What are proteins?
The term to describe similar physical structures adapted for different functions between related species.
What are homologous structures?
The transfer of genetic variation from one population to another through the migration of individuals.
What is Gene Flow?
These are the two classes of barriers that can lead to speciation.
What are prezygotic and postzygotic?
This is the main way new alleles are introduced to the Gene pool of bacteria.
What are mutations?
The complete set of genetic material present in an organism.
What is genome?
Related organisms share similarities in this multicellular stage of development.
What is embryo?
A measure of an organism's ability to survive and successfully pass on its genes to the next generation.
What is Fitness?
Animals and plants can change as a ______________ but not as an individual.
What is species?
These chemicals are able to kill bacteria but not viruses.
What are antibiotics?
This is the phenotype outcome you expect from incompletely dominant inheritance.
What is intermediate? (mixed)
Scientists compare sequences of which molecule to investigate how closely related organisms are?
what is DNA?
The combined total of all the different genes and alleles present within a given population.
What is Gene pool?
This diagram shows relationships between different organisms based on DNA or anatomical evidence.
What are phylogenetic trees?
Some scientists say that viruses are non-living because of their inability to do this without a host.
What is reproduce?
These 2 mechanisms of sexual reproduction drive evolutionary diversity.
What is crossing over and recombination?
A human appendix is an example of this type of anatomical structure.
What is vestigial structure?
The process where unrelated species independently evolve similar traits because they occupy similar environments.
What is convergent evolution?
These are the 5 forces that can lead to the evolution of a new species.
What is natural selection, non-random mating, mutations, Gene Flow, genetic drift (small populations)?
Explain why bacteria can become resistant to antibiotics.
