Vocabulary
"a group of organisms of the same kind (in one or more populations) that do not reproduce with organisms from any other group"
what is a species?
What is a random change to a gene or DNA that can result in a new trait.
Mutation
A dog has brown fur. This brown fur is a type of...
Trait
Rough-Skinned Newts are always very poisonous. True / False?
Individuals inherit their ______ from their parents
What are genes, alleles, gene versions, traits, phenotypes or genotypes
"a trait that makes it less likely that an individual will survive in a specific environment"
what is a non-adaptive trait?
Why do the birds have strong beaks?
Due to the change in environment, beak was the adaptive trait, therefore these birds passed on this trait and the population changed over time.
Adaptive traits do this over many generations.
What is become more common?
What changed in the Newt population over time?
What is TTX posion.
Mutations always become more popular within a population. True or False?
False
"the process in which two parents pass on their genes to create offspring"
what is sexual reproduction?
This is a graph with which all members of a species can be compared.
What is a histogram?
Would the color of the ostrilopes impact their survival if there were NO Carnithons in the environment? Why?
No, they don't need to blend into their environment if there are no predators.
This is the natural predator of the rough-skinned newt
What is the garter snake?
Variation is the amount of different types of traits for a feature. True or False
True
"any difference in traits between individual organisms"
what is variation?
What type of mutation trait has no effect on the population.
What is neutral
This is an adaptive trait for the ostrilopes when the environment got colder was?
More fur/ longer fur
A higher poison level of the rough skinned newts is considered what kind of trait?
Adaptive trait
Genes are instructions for making ______________ molecules, which determine the organism's traits.
Protein
the number of individuals with each trait in a population"
what is distribution? (EXTRA)
At time 1, the population had the same number of brown and white foxes. At time 2, after many generations, there were many more brown foxes and fewer white foxes in the population. What likely happened?
The environment became brown. With each generation, more brown foxes survived long enough to pass on the gene for brown fur to their offspring
If a trait is present in the starting generation, it will always be present as time goes on. True or False? Why?
False, sometimes starting traits will die off over time if the environment changes.
How did the level 10 poison trait appear in later generations of newts? Why did they become more common than other newts without that trait?
Mutation, they were able to survive longer and reproduce more than the other newts.
Give an example of a mutation.
adaptive - Poison level 10 for newts
