What aspects of development do maternal-effect genes control?

Key Concepts

Maternal-Effect Genes

Maternal-effect genes are genes expressed in the mother that produce mRNA or proteins, which are then deposited into the oocyte (egg) during oogenesis. These maternal products influence the early development of the embryo, affecting processes such as cell division, axis formation, and initial patterning.

Embryonic Development

Embryonic development refers to the series of stages that an embryo undergoes from fertilization to the formation of a fully developed organism. Maternal-effect genes play a crucial role in this process by regulating the timing and expression of developmental pathways that guide the embryo's growth and differentiation.

Gene Regulation

Gene regulation involves the mechanisms that control the expression of genes, determining when and how much of a gene product is made. In the context of maternal-effect genes, the regulation of these genes is vital for ensuring that the correct proteins and RNAs are available at the right stages of embryonic development, influencing the overall developmental trajectory.
