What is a structural adaptation?
A trait that helps an organism survive
Where the DNA is stored in a cell
What is the nucleus?
The physical traits of an organism
Something's preserved remains
What is a fossil?
Ducks flying south for the winter
What is a behavioral adaptation?
A trait that is neutral or harms an organism
What is a disadvantage?
The part of a cell that generates power
What is the mitochondria?
The genes in an organism represented by uppercase or lowercase letters
What is a genotype?
The age of a rock or fossil compared to another
Two things are bred together to have a desired trait
What is selective breeding?
Produces reproductive cells
What is meiosis?
The lowercase allele
What is a dominant allele?
The exact age of a rock or fossil
What is the absolute age of rocks and fossils?
One organism gets a new trait, and then it slowly spreads throughout the population
What is mutation?
An organism's DNA is exactly replicated to make a new organism.
What is cloning?
Grows body cells like skin and hair
What is mitosis?
The lowercase allele
What is a recessive allele?
A fossil with bones, shells, or leaves
What is a body fossil?
The living things with the most helpful adaptations survive(survival of the fittest)
What is natural selection?
Removing DNA and replacing it with the desired trait
What is genetic engineering?
The DNA of a cell replicates(hint: mitosis, meiosis, or both)
What is both?
The chances of having homozygous recessive offspring if the genotypes are AA and Aa
What is 0%?
They show us history and teach us about the facts of the earth
