When a pair of alleles are not the same for a single trait
What is heterozygous?
Nonliving components of an ecosystem such as air, water and rocks
What is abiotic factor?
Organisms can get used to and thrive in an environment so they can reproduce.
What is adaptation?
This is the oldest type of evidence to prove extinct organisms once existed.
What are fossils?
Changes in DNA sequences
Skin color, flower petal color, wavy hair
What is incomplete dominance?
When a population grows as a rapid pace and many times is outgrowing the resources available
What is exponential growth?
Variation is assured when organisms reproduce in this fashion.
What is sexual reproduction?
Some fish and salamanders that live in blackout caves still have eyes, but they no longer serve any functional purpose.
What is vestigial structure?
Small populations are separated from larger populations and begin to evolve within themselves.
What is the Found Effect?
This image will tell inform you of gender and chromosome number
What is a karyotype?
Consumers are also know as this
What are heterotrophs?
Evolution would not take place if this didn't exist in populations
What is variation?
You can tell organisms are common ancestors due to their body parts being built in similar fashion or patterns
What are homologous structures?
Each living organism has a role within the ecosystem
What is a niche?
A trait such as height, hair color and eye color that are controlled by multiple genes
What is polygenic?
You've hit this population mark when organisms begin to compete at a high level and sometimes even starve due to lack of resources.
What is Carrying Capacity?
In a population of spiders, the average sized spiders are selected against because predators can see them easily.
What is Disruptive Selection?
This is the most accurate evidence that can be used to show relationships between organisms.
What is DNA or Amino Acid comparison?
Organisms move to other areas, decreasing the overall population.
What is Emigration?
You can use these to compare the number of genotypes and phenotypes from a Punnett Square
What are ratios or percentages?
This type of diagram is used to show the energy transferred to organisms throughout the food web and how it reduces by 90% at each level.
What is an ecological pyramid?
How often a dominant or recessive allele is present within an entire population of organisms.
What is allele frequency?
You can see relationships between different species throughout a period of development
What is embryology?
What is Mr. Rinehart's favorite food?
What are tacos?
