What are alleles?
Variation of a gene
100
What is mitosis?
Mitosis is division of cells where one parent cell divides into two exactly identical daughter cells.
100
If you are a purebred, what does that mean?
You have two of the same traits
100
Give me an example of extinction.
dodo bird.
100
What is artificial selection?
Process of selecting and breeding organisms with desired traits.
200
What are chromosomes?
packages of DNA fit into cells
200
What is meiosis?
One parent cell divides into four cells which contain only have half the amount of DNA in a normal cell.
200
If you have two recessive traits, are you a hybrid?
No.
200
What is extirpation?
Extinction from one area.
200
Give an example of ex situ conservation.
zoos, greenhouses/botanical gardens, seed banks.
300
What are the four chemicals that make up DNA?
Adenine and Thymine, Cytosine and Guanine.
300
What could a multicellular organism use mitosis for?
growth and cellular repair.
300
There is a black haired dominant trait and blonde haired recessive trait. Can you have blonde hair if you were a hybrid of these traits?
No. The recessive trait never can be expressed because we have a dominant trait.
300
What is overspecialization?
when an organism has adaptations in a narrow set of environment conditions.
300
What is in situ conservation?
Conserving/maintaining of populations of wild organisms in their own ecosystems.
400
What does DNA stand for?
DeoxyriboNucleic Acid
400
What is meiosis used for?
sexual reproduction
400
If you had a white flower who cross breeds a red flower and their baby is pink, what is this an example of?
incomplete dominance.
400
Why is the introduction of non native species so dangerous?
They have no natural predators in the area. They were kept in check in the predators in the other environment.
400
What is an advantage of artificial insemination?
Can transmit gametes long distances without having to take the organism to the other organisms.

Make a mind map showing the relation of DNA, Genes and chromosomes
DNA - Chromosomes - Genes - DNA. DNA is put into little packages called chromosomes, chromosomes contain genes, genes is an uninterrupted segment of DNA.
500
What is this process? Meiosis or mitosis?
Meiosis
500
Complete this Punnett Square if the father was purebred recessive and the mom was a hybrid.
500
Name three reasons for extinction/extirpation.
catastrophic events, floods, fires, overhunting, overspecialization, habitat destruction, disease, overpopulation (lack of food),

In Alberta, what does ESCC do for COESWIC?
ESCC makes a document every 5 years that lists all endangered and threatened species, which COESWIC takes into account when making policies and programs for the protection of the endangered/threatened species.
