Mitosis
Describe the genetic relationship between parent and offspring.
They are genetically identical.
What is the advantage of sexual relationship (to a population)
The four gametes produced are all different.
Which form of cell division provides variation?

What is genetics the study of?
Inherited characteristics called traits
