The embryonic stage is a critical phase in prenatal development, spanning from fertilization to the eighth week, during which the foundations for all major body structures and organs are established. This stage is characterized by rapid cell division, differentiation, and the formation of essential systems, making it highly sensitive to genetic and environmental influences.

Prenatal development is the process by which a baby develops from a single cell after conception into an embryo and then a fetus, culminating in birth. This complex process is divided into three stages: germinal, embryonic, and fetal, each characterized by significant growth and developmental milestones essential for a healthy birth.

Fertilization is the process where a sperm cell and an egg cell unite to form a zygote, initiating the development of a new organism. It is a critical step in sexual reproduction, ensuring genetic diversity and the continuation of species.

Differentiation is a mathematical process used to determine the rate at which a function is changing at any given point, providing insights into the behavior and properties of the function. It is fundamental in calculus and has applications across various fields such as physics, engineering, and economics, where understanding change and motion is crucial.

Genetic influences refer to the impact of genes on the development and traits of an organism, encompassing both inherited genetic material and its interaction with environmental factors. Understanding genetic influences is crucial for studying heritability, genetic disorders, and the role of genetics in complex traits and behaviors.

Genetic Influences

Environmental influences encompass the various external factors that can affect an individual's development, behavior, and overall well-being, ranging from physical surroundings to social interactions. These influences can be both positive and negative, shaping the way organisms adapt and respond to their environment throughout their lifespan.
