What is a genetic simple definition?
Genetics is the scientific study of genes and heredity—of how certain qualities or traits are passed from parents to offspring as a result of changes in DNA sequence. A gene is a segment of DNA that contains instructions for building one or more molecules that help the body work.
What is genetic factors in child development?
As we all know, the inherited genes from our parents influence everything from height, eyes colour, hair colour and other physical characteristics, to intelligence, behavioural patterns and personality traits. Who we are today is shaped by our genetic background as well as environmental influences.
What is genetic and environmental factors?
Your genes hold the basic instructions for your body to grow and function, but they are far from the only thing controlling your traits. Most traits are shaped both by a person’s genes and by environmental factors. Environmental factors include everything outside of DNA that affects your traits.

Genes influence each individual’s behavioral and psychological characteristics, including intellectual ability, personality, and risk for mental illness—all of which have bearing on both parents and children within a family.
How genetic factors affect growth?
Major growth genes exert a fundamental effect on human growth (1), and include the genes for endocrine, skeletal, and malformation disorders. They are relevant to growth failure (or overgrowth) that can be recognized as a single gene disorder.
How does genetic factors affect growth and development?
Heredity influenced the rate of growth of early maturers or late maturers. Parent – offspring correlation in regard to height from birth to maturity for each are and sex has been reported. Chromosomal abnormalities suggest genetical control on growth.
What genetic factors determine human characteristics?
Genes are instructions that dictate how a person’s body is made, in the same way that blueprints are instructions to build a house. Information from genes let the body know what characteristics a person will have, like if they will have hairy or hairless ears and/or a small or big chin.
What are environmental factors?
Environmental factors include temperature, food, pollutants, population density, sound, light, and parasites. The diversity of environmental stresses that have been shown to cause an increase in asymmetry is probably not exclusive; many other kinds of stress might provide similar effects.
How do genetic factors affect public health?
