Answer:

The statement that is correct is that all cells have the same genes, but different genes are active in different cells.

Explanation:

Differentiation or specialization is a function that cells possess and is what allows them to have different types of cells and tissues.

Cell differentiation depends on genetic regulation, a mechanism that determines the specific genes that are expressed in a cell or tissue type.

All cells contain the same DNA, which is organized into chromosomes and contain the genes that determine specific characteristics. There is cell differentiation because some genes can be expressed and others are suppressed, all due to genetic regulation.

The other choices are wrong because:

The eyes look different from the liver, because they have the same genes, but only some are expressed.
Differentiated cells and tissues do not lose their genes.
All cells have DNA.
