Causation
The variable that is controlled in an experiment is called…
The independent variable
Proteins are produced when ____ are expressed
Genes
A _______ between variables, however, does not automatically mean that the change in one variable is the cause of the change in the values of the other variable.

According to ___________, only one of the two gene copies present in an organism is distributed to each gamete (egg or sperm cell) that it makes, and the allocation of the gene copies is random.
Law of Segregation
When an organism makes gametes, each gamete receives just one gene copy, which is selected randomly. This is known as the
law of segregation

Segregation
Independiente assortment
