Cell Division
Heredity
Natural Selection
Mutation
Genetic Engineering
100
This is the division of cells to form duplicates.
What is mitosis?
100
Homologous chromosomes are from these two people.
What are your mom and dad?
100
This person came up with the theory of evolution by natural selection.
Who is Charles Darwin?
100
Mutations result in a change in this molecule, which stores genetic information.
What is DNA?
100
Genetic engineering means making changes in this molecule in your body.
What is DNA?
200
Before mitosis occurs, the cell needs to do this to the DNA.
What is replicate the DNA?
200
These words mean that one gene is more likely to show up even when the other gene is present.
What are dominant and recessive?
200
According to the theory of natural selection, animal traits change over time because of pressure from this.
What is the environment?
200
During DNA replication, this happens to cause mutations.
What is an error in DNA replication?
200
This is a process where "desirable genes" in a group of organisms are kept, while "undesirable genes" are removed. An example of this is keeping certain people from having children.
What is eugenics?
300
This will happen to these sister chromatids during telophase of cell division.What is separate?
300
TT x tt produces offspring. If two of the offspring produce their own offspring, the percent chance of getting Tt is this.
What is 50%?
300
Charles Darwin observed animals in this place to come up with the theory of natural selection.
What are the Galapagos Islands?
300
Random mutations can cause bacteria to develop this trait that makes them harder to kill.
What is resistance to antibiotics?
300
Crops are commonly genetically modified to make them resistant to this.
What are weed-killers (herbicides), disease or pests?
400
In meiosis, one cell produces this many gamete cells.
What is 4?
400
A tall plant crossed with a short plant produces offspring that are 50% tall and 50% short. What are the genes of the parents?
What is Tt and tt?
400
Darwin observed that finches on different islands had evolved different forms of this trait.
What is the beak shape?
400
Mutations cause a change in DNA, which results in a change in these biological molecules.
What are proteins?
400
The most common method of cutting out parts of DNA involves using this kind of protein.
What is an enzyme?
500
In meiosis, the homologous chromosomes do this, which they don't do during mitosis.
What is crossover?
500
Gregor Mendel experimented with plants that only had one dominant and one recessive allele. Human blood type (A, B, AB, O) has this many dominant alleles.
What are 2?
500
Instead of being systematic process, evolution by natural selection suggests that evolution is more like this kind of process.
What is a random process.
500
If a mutation caused the DNA sequence CGATGG to become CATGG, it is called this.
What is a base pair deletion?
500
Modifying the genes of an organism means modifying the production of these biological molecules in the cells of that organism.
What are proteins?
