These are the nucleotides that make up your DNA
A, T, G, C or adenine, thymine, guanine, cytosine
100
This is the term for a letter representing a specific version of a gene
What's an allele
100
A trait that makes an organism more fit for its environment
What's an adaptation?
100
This is the term for a population of organisms that can reproduce and produce offspring that can also reproduce
What is species?
100
The maximum amount or capacity that an ecosystem can hold.
What is the carrying capacity?
200
This is term for when an RNA copy of DNA is made
T A C bonds with A U G
What is transcription?
200
Hanging earlobes is a dominant trait.
What would be the genotype of a heterozygous person with hanging earlobes? Use the alleles "a"
Aa
200
Things that drive what a population looks like, such as predators or food acquisition.
What are environmental/selective pressures?
200
These two fish were separated by the isthmus of panama. What led to this reproductive isolation?
What is geographic isolation?
200
This is the carrying capacity of the flies in this ecosystem?
What is 350 flies?
300
DNA codes the instructions for making these
What are proteins?
300
Hanging earlobes is a dominant trait.
What sort of earlobes would a person with the genotype aa have?
What are attached earlobes?
300
The term describing an organism being well suited for its environment.
What is "Fit" or "Fitness"?
300
These limbs show that various species share the same type of bone adapted for different purposes and environments. What is the name of this evolution evidence?
What are homologous structures?
300
This is the day that the carrying capacity is met?
What is day 45?
400
The following DNA strand
T A C G C C T G A
Has the first T deleted. What is the name of the change that occurred?
What is a "frameshift mutation"
400
Hanging earlobes is a dominant trait.
A homozygous dominant person is crossed with a heterozygous person. What are the chances that their child will have attached (non-hanging) earlobes?
0% aa
400
Also known as the concept "Survival of the fittest" this is when a population changes overtime to have a phenotype that makes it more fit for its environment.
What is natural selection?
400
Looking at these show that many organisms develop similarly in their early stages, suggesting relation and common ancestry.
What are embryos?
400
This is the name of things that affect the carrying capacity of a species?
What are limiting factors?
500
Green eyes are recessive. A child with green eyes is born to a mother with green eyes? What is the chance that the father be homozygous dominant?
0%
500
Hanging earlobes is a dominant trait.
A homozygous dominant person is crossed with a heterozygous person. What are the chances that their child will be able to pass along the trait for attached earlobes (non-hanging)?
50% Aa
500
This is the term for a mechanism of evolution that in which an adaptation becomes more common in each generation.
What is descent with modification?
500
This is what's absolutely necessary for a new species to diverge.
What is reproductive isolation?
500
How you would expect the carrying capacity to change if food for flies increased.
What is "increase" or "go up?"
