Genes are the term for groups of genetic code, as DNA, that define inherited traits. Genes control all of your physical traits, such as height, eye color, hair color, predisposition for diseases such as Diabetes, and, it is believed, predispositions for behavior as well. They are literally the coding for who you are, both physically, and in some part personality wise. however, your personality is also greatly affected by environment.
In a nutshell: genes are the instructions to your cells for your physical traits and the predisposition to certain personality traits.
Genes inherited from both the mother and father influence embryo development by determining traits such as physical characteristics, health, and behavior. These genes provide the instructions for how cells grow and function, ultimately shaping the development of the embryo into a fully formed individual.
In the past century there will be a different classification of human evolution
Human genetics is the study of how genes influence human traits and characteristics. It explores the inheritance of traits from parents to offspring and how variations in genes can impact health, development, and disease susceptibility in humans. This field also investigates the role of genetics in understanding evolutionary relationships among different human populations.
Human traits are controlled by a combination of genetic factors (inherited from parents), environmental factors (such as diet and lifestyle), and epigenetic factors (changes in gene expression without changes in the underlying DNA sequence). These factors interact in complex ways to influence the development and expression of human traits.
Genes are segments of DNA that contain instructions for making proteins, which are essential for the development of traits and characteristics in living organisms. Different combinations of genes determine an organism's traits, such as eye color or height. Genes can influence traits through processes like protein synthesis, gene expression, and inheritance of genetic information from parents.
what can somtimes influence expression of genes
Homeotic genes are critical regulatory genes that control the development of anatomical structures in organisms. They determine the identity and positioning of body segments by specifying which body part will develop in a particular segment during embryonic development. By encoding transcription factors, homeotic genes influence the expression of other genes, thus orchestrating the complex processes of morphogenesis and pattern formation. Mutations in these genes can lead to significant developmental abnormalities, illustrating their essential role in proper organismal development.
Genes that are in control of other genes or biological processes are often referred to as "regulatory genes." These genes play a crucial role in regulating gene expression, determining when and how much other genes are activated or suppressed. They can include transcription factors and other elements that influence cellular function and development.
The human genome contains about 24,000 genes.
Yes, bacteria can be genetically modified to express human genes. This is commonly done in biotechnology and genetic engineering for purposes such as protein production, drug development, and studying genetic diseases. The human genes are inserted into bacterial cells, which then produce the corresponding human proteins.
They include environment, races, heredity, learning, sex and nutrition. Growth and development is the process of a human being advancing from childhood to maturity.
Genes play a crucial role in fetal development as they provide the instructions for building and maintaining the body's structures and functions. They regulate processes such as cell division, differentiation, and organ formation, ensuring that the fetus develops properly. Additionally, genes influence traits such as growth rates, physical characteristics, and susceptibility to certain conditions, making them essential for healthy development and the overall viability of the fetus.
