There isn't a single series of genes that completely controls organ and tissue development in embryos. Instead, it's a complex interplay of multiple gene families and regulatory networks that work together. Here's a breakdown of some key players:

1. Homeobox Genes (Hox Genes): These genes play a crucial role in patterning the body axis during development. They determine the identity of different body segments and influence the development of organs and tissues within those segments.

2. Transcription Factors: These proteins bind to DNA and regulate gene expression. They are essential for turning genes on and off at the right time and place, controlling the development of specific tissues and organs.

3. Signaling Pathways: These are complex networks of molecules that communicate between cells, influencing cell fate and differentiation. Some key pathways involved in organ development include Wnt, Hedgehog, and TGF-beta signaling.

4. Morphogens: These are signaling molecules that create gradients across the developing embryo, influencing the identity of cells in different locations.

5. Extracellular Matrix (ECM) Components: These molecules provide structural support and influence cell adhesion, migration, and differentiation, ultimately contributing to organ formation.

It's important to remember that development is a highly dynamic process where these different gene families and regulatory networks work together in intricate ways. A single gene may not fully control the development of an organ, but rather contributes to a complex network that influences the fate of many cells.

Instead of a single "series", we can talk about gene regulatory networks that control organ development. These networks are interconnected and involve multiple genes and signaling pathways working together.
