Biological fitness definition
(an organisms health) - ANS "a measure of the extent to which an individual's genotype
is represented in the next generation."
Biological fitness - ANS Adaptation, survival, and reproduction
Does that trait allow an organism to have more offspring relative to other
individuals in the population that have a different version of that trait
Viable offspring - ANS alive and generally able to survive typical conditions
Biological adaptation - ANS the ability of an organism to react to changes in
environment
Adaptation - ANS Adaptation is relative so it has to be thought about in context and what
environments those organisms are living in
Traits that increase fitness - ANS Higher fitness= more copies of the trait passed to future
generations

Ultraviolet radiation - ANS Very energetic that it can penetrate human cells
Can wreak havoc within the cells and cause mutations in DNA
MC1R - ANS one of the many genes linked to skin pigmentation
Folate - ANS essential nutrient that needs to be protected from UV radiation
○ This is where melanin comes in
evolution - ANS is the unifying theory of biology
biological evolution - ANS a change in frequency of a genetic trait in a population over time
Scienitific Theory - ANS a conceptual framework that explains existing facts and predict new
ones
gene pool - ANS all of the alleles in all of those individuals of a population together
artificial selection - ANS humans or other organisms are choosing which members survive
and pass on thier genes
mutation/recombination - ANS forming of new alleles
gene flow - ANS movement of genes from one population to another
migration - ANS movement of individuals between populations within one species
