C)differences in gene copy numbers.
D)morphogenesis.

Question

Quizplus · Accepted Answer

Cellular differentiation is the process by which a less specialized cell becomes a more specialized cell type with a more specific function. This is largely due to differences in gene expression, where certain genes are turned on or off in order to achieve a specific cell type. Differences in DNA sequences and gene copy numbers can also contribute to differentiation, but it is primarily controlled by gene expression. Morphogenesis refers to the physical process of cellular organization to form tissues and organs, and is separate from cellular differentiation.
