All cells in an embryo have the same genes, yet they express different subsets of genes. Selective gene expression is therefore the basis of ____.
A)cleavage
B)cell differentiation
C)fertilization
D)gamete formation
E)organ maturation

Question

Quizplus · Accepted Answer

Selective gene expression is the basis of cell differentiation, as cells in an embryo differentiate and develop into specialized cell types with specific functions. Cleavage refers to the rapid cell division that occurs in the early stages of embryonic development, fertilization is the fusion of gametes to form a zygote, gamete formation refers to the formation of specialized male and female reproductive cells, and organ maturation refers to the final stages of organ development and function.
