What is Meiosis?
The study of genes and inheritance in living organisms.
What is genetics?
Why does a Punnet Square use capital and lowercase letters?
Capital = Dominant Trait
Lower Case = Recessive Trait
The physical trait observed in an offspring.
This is where Mitosis takes place and produces many types of _______ cells. (stomach cells, red blood cells, lung cell, etc)
What is body cells?
This is where Meiosis takes place and produces _______ and ________ cells.
A section of DNA that codes for a particular trait.
What is a gene?
Name two traits that could be inherited from a parent?
Examples: hair color, eye color, height, skin color, freckles, etc..
For some traits, only one copy of a particular gene is needed to show a given trait. These genes are stronger and take over.

What is genetic variety?
The person who first studied heredity and the passage of traits from one generation to the next and known as the "father of genetics".
