Process of Science
Can a hypothesis be supported or not supported
True or False?
True
What is the founder effect and give an example
When a population is decedents of a small group of organisms that *colonized an area
What happened to our tails?
Explain it
Fell off
Why don't similar genotypes always produce the same phenotype
Parents alter their phenotypes and pass on this phenotype to progeny
What is the difference between genotype and phenotype
Pheno- Phyiscal
Geno- Genetical
What are the limitations of an observational study?
You cannot control anything really in an observational study
What is the difference between haploid and diploid?
the difference in the number of chromosomes and sets of chromosomes
Explain Descent of Modification
Finch Example
How can variation occur?
can be due to genes
can be due to environment
can be due to interaction of genes with environment
What is an allele?
Genetic makeup on a chromosome
Also give an example of it
A statement that explains what the outcome of an experiment would be if there was no statistical difference between the controlled group and experimental group.
they can survive yes but they must reproduce in order for evolution to occur
What are mutations?
Source of all new genetic variation
•Mutations can be adaptive or non-adaptive, they
occur randomly.
•Most mutations are harmful or have no effect, but
some may be useful
Natural Selection is evolution
True or False?
False
What is the Bottleneck effect and give an example of it
When the gene pool of a population is reduced drastically by a random natural event
What is an independent variable and a dependent variable and where could they be possibly located on a graph?
Independent Variable – The variable that is manipulated in studies because it influences the other variable.
Dependent Variable - The variable that is being tested because it is impacted by the manipulated variable
X-axis – the axis that is horizontal and is where the independent variable goes
Y-axis - the axis that is vertical and is where the dependent variable goes
What is natural selection?
Natural selection and survival of the fittest are the same thing
True or false
When differences in genotype causes differences in survival and reproduction in different individuals
False
Natural selection is based on all of the following except... [choose one]
genetic variation exists within populations
the best-adapted individuals tend to leave the most offspring
individuals who survive longer tend to leave more offspring than those who die young
individuals adapt to their environments and thereby evolve
individuals who survive longer tend to leave more offspring than those who die young
What does HWE help predict
If evolution is occuring or not
What are Experimental Groups
The group that has a variable that is changed and being tested.
What is the difference between a hypothesis and a prediction
Must give an example as well
Prediction is an if, then statement. Further explains your hypothesis
A hypothesis is a statement that explains an observation. It must be testable.
What is gene flow and give an example of it
The flow or transfer of genetic material from one population to another
How can humans have affect on natural selection and mutations?
They can pick partial things
Lamarckism: 2 principles
What are they and explain
use and disuse and inheritance of acquired characteristics
What is a simulation
A study that mimics or simulates real world systems to try to better understand the real-world system
