Yes, environmental factors can interact with genes and influence development. For example, exposure to certain chemicals or nutrients can affect gene expression and alter developmental processes.
Do all genes play a role in development?
No, not all genes are directly involved in development. Some genes are responsible for basic cellular functions, while others may be specific to certain tissues or stages of development.
What can researchers learn from studying genetics and developmental biology?
By studying genetics and developmental biology, researchers can gain insights into how organisms develop and grow, identify genetic factors that contribute to developmental disorders or diseases, and potentially develop new treatments or interventions based on this knowledge.
What is developmental biology?
Developmental biology is a field of biology that studies the processes by which an organism grows and develops from a single cell to a fully formed individual. It explores the molecular, cellular, and genetic events that occur during development.
