Gene structures, adaptive behavior, and evolutionary traits are covered in these biology flash cards.
There are 20 flash cards in this set (4 pages to print.)
1. Print out the cards.
2. Cut along the dashed lines.
3. Fold along the solid lines.
Sample flash cards in this set:
|Analogous structure||Structures that do not have a common evolutionary origin but are similar in function.|
|Artificial selection||Process of breeding organisms with specific traits in order to produce offspring with those same traits.|
|Camouflage||Structural adaptation that enables a species to blend with their surroundings|
|Homologous structure||Structures with common evolutionary origins; can be similar in arrangement, function or both.|
|Mimicry||Structural adaptation evolved in some species where one species resembles another.|
|Natural selection||Mechanism for change in populations; occurs when organisms survive, reproduce and pass their traits on.|
|Vestigial structure||Structures that has no function in a present-day organism but was probably useful to an ancestor.|
|Allelic frequency||Percentage of any allele in a population's gene pool.|
|Directional selection||Natural selection that favors individual with one extreme of a trait.|
|Disruptive selection||Natural selection that favors both extreme variations of a trait.|
|Gene pool||All of the alleles in a populations genes.|
|Genetic drift||Alteration of allelic frequencies in a population by chance events.|
|Genetic equilibrium||Condition in which the frequency of alleles in a population remains the same over generations.|
|Variation||Differences with in a species that is provided by mutations and sexual reproduction.|
|Speciation||A process of evolution of new species that occurs when members of similar populations no longer interbreed to produce fertile offspring.|
|Stabilizing selection||Natural selection that favors the average individuals in a population.|
|Adaptation||Inherited features that make a species more suited to survive and reproduce in its environment.|
|Adaptive radiation||Divergent evolution in which ancestral species evolve into an array of species to fit a number of diverse habitats.|
|Evolution||The gradual accumulation of adaptations over time.|
|Over production||More offspring are born than can survive to reproduce.|
