What are fossils?
Preserved remains or
traces of ancient organisms.
If an organism has a genotype of TT, we would call them?
Homozygous Dominant.

F1
If something is a hybrid, what term have we used to describe that?
Heterozygeous
T/F: Survival of the fittest is referring to the strength of the organism.

False
Changing the genetic makeup/traits of a child is known as what?
Designer Babies
Recessive traits are only expressed if...
The dominant trait is not present.
What is the genotype ratio of the following cross:
Tt x Tt
Result in a 1:2:1
(TT,Tt,Tt,tt)
Is this artificial or natural selection?
Peppered Moths: During the
Industrial Revolution in England,
darker moths became more common
due to soot-covered trees.

If a dog with brown fur is crossed with a dog with white fur, and the offspring has white and brown fur, what is that called?
Codominance
Is the following artificial or natural selection?
Crops: Corn has been bred
from wild grasses for size and
sweetness.
Artificial Selection
What are fossils that reveal steps between major groups, such as fish to amphibians. (Bonus if you can name the organism that was the step between fish to amphibians)
Transition Fossils (Tiktaalik)
What era of geologic time was dominated by dinosaurs?
Mesozoic Era
Chemical factors that determine traits are called?
Genes
What is it called when one allele is not completely dominant over another?
Incomplete Dominance
Darwin was looking at finches with different beak sizes. Why did they have different sized beaks? (Be specific)
Natural selection due to the size of food (seeds) they need to open to eat.
What era are we currently in?
Cenozoic Era
