the selective loss of certain genes from the genome

Explanation:

Cell differentiation involves certain changes in the size and functions of cells. Cell differentiation is usually common when organisms are at their formative stage. The cells usually become bigger and the functions become restricted.

This is made possible through the loss of certain genes from the genome. It gives rise to certain vast functions of the cells being dropped and becoming more specialized for more efficiency.
