group of the same type of organism from the same area
population
How can we describe a population?
Distribution (number of individuals with a trait) and variation (number of traits)
What is an adaptive trait?
Trait that makes it more likely that an individual will survive in a specific environment
What is a gene?
Instructions for making protein molecules, determine organisms traits
What is my favorite color?
Green
Specific characteristic of an organism (can be passed down)
trait
Is this histogram high in variation or distribution?
Variation (horizontal on the graph)
Can an organisms can change their traits during their life time?
No, you are born with the traits you are given.
Where does a individual get their genes?
From their parents
What high school did I go to and what year did I graduate?
Millard North, 2020
group of individuals born about the same time
generation
Is this graph high in distribution or variation?
Distribution (Vertical)
What is the adaptive trait?
Color yellow
What is a protein molecule?
Large molecule that performs important functions inside of an organism (cells)
What sorority was I in?
Alpha Omicron Pi
number of individuals with each trait in a population (vertical)
Distribution
What happened to the Newt population?
Poison became an adaptive trait. Newts with poison were more likely to survive and reproduce.
What is a non-adaptive trait? Give an example
Trait that prevents you from surviving and reproducing.
Does an organism always have offspring with adaptive traits?
No, non adaptive traits can also be passed on. Those with non adaptive traits are less likely to survive and reproduce.
When is my birthday?
difference in traits between organisms (horizontal)
Variation
If the environment is going from soft seeds to tough seeds, how will the histogram change and why?
In a lush, green forest lived a group of rabbits. Among them was a unique rabbit named Leo. While most rabbits had a standard brown fur coat, Leo had a white fur coat that stood out against the vibrant greens and browns of the forest. At first, his friends worried that he would be easily spotted by predators. However, as winter approached and the snow began to blanket the forest, Leo found himself blending in perfectly with the snowy landscape, while his brown-furred friends became very visible to the predators prowling through the white snow.
What is the adaptive trait?
Leo's white fur coat
How do some traits become more common over generations and others become less common?
Those with adaptive traits survive and reproduce at a higher rate then those with non adaptive traits. This makes their genes more common in a population.
