1)Identifying genes whose products are involved in the differentiation of specific phenotypes
2)Identifying genes whose products are involved in the dedifferentiation of genotypes
3)Identifying proteins whose products are not involved in the differentiation of specific phenotypes

B) 2
C) 3
D) 1 and 3
E) All of these are correct.

Identifying genes whose products are involved in the differentiation of specific phenotypes is the most appropriate method for studying developmental pathways as it identifies the specific genes and their products that are involved in the differentiation of cells into specific phenotypes. Identifying proteins whose products are not involved in differentiation (Option C) is not relevant to studying developmental pathways, and identifying genes whose products are involved in dedifferentiation (Option B) is not an appropriate method as dedifferentiation is not a common developmental pathway. Option D is partially correct, but Option A is the most appropriate choice.
