Wild-type traits are more often seen in populations, but are not always expressed by dominant alleles.

A cell spends _______ of its time in Interphase.  

Radiometric Dating is 100% accurate and based on the decay of radioactive isotopes. 

[Oncogenes] are genes that cause cancer.  [Proto-oncogenes] are normal genes capable of becoming cancer causing genes.  While proteins known as [growthfactors] stimulate cellular division.  The [tumorsupressing] are genes responsible preventing uncontrolled cell growth.  These genes could be mutated leading to them becoming inactivated, and leading to [cancer]. 

Carcinogens are cancer-causing agents found in the environment.

The 3 main causes of evolutionary change are [GeneticDrift], [GeneFlow], and [NaturalSelection].  [Geneticdrift1] is the change in a gene pool that can result in the loss of alleles in a population.  [Geneflow1] is genetic exchange with another population, and may result in the gain or loss of alleles. Overall [Naturalselection] is the most important.  

Match what’s correct about the two stem cell types. 

Genetic Drift is a random change in the gene pool due to chance.  [cheetah] are the poster animal/example of a species that’s gone through a specific Genetic Drift.  The [Founderseffect] is when a few individuals colonize an isolated habitat, and their gene pool differs from the parent population.  While the [bottle] is a drastic reduction in population size, and are the parent population.  

A process in which organisms with certain inherited characteristics are more likely to survive and reproduce than are individuals with other characteristics is known as Natural Selection.
