Genotypes: 50%Bb and 50%bb
What is the meaning of Microevolution?
Microevolution: Evolutionary change within a species.
What is artificial Selection?
Artificial Selection: process in where an animal or plant is breed with another desired plant or animal.
What is a fossil?

What is the function of the cell wall in a plant?
Function: Maintain a structure of the cell shape to hold together all the cell organelles.
What are phenotypes?

What is the Law of Superposition?
Law of Superposition: The oldest is always on the bottom while the youngest is always on top when coming to layers.
What cells do MITOSIS and MEIOSIS produce?
Mitosis: Two identical daughter cells in the body
Meiosis:Gametes
What are genotypes?

What is an intrusion?
Intrusion: An intrusion is when a rock pushes into another rock going through it so intruding in the layers making an intrusion.
Why is the cytoplasm organelle of a cell important?
The cytoplasm is important because it holds all of the organelles together in its sticky like substance.
How are two daughter cells made?
They are made by Mitosis.
What type of microevolution is where the population slowly changes and then changes frequently?
Genetic Drift
What is the purpose of artificial selection?
Artificial selections purpose is to have desired traits in an organism.
Is the top layer of a rock the youngest or is an intrusion the youngest?
An intrusion is the youngest.
