The phenomenon by which living organism transmit parental characters to their off springs is called heredity.
The characters of the parents which are transmitted to their off springs are called hereditary characters. Heredity is also known as inheritance.
Genetics is a branch of biology concerned with the study of genes, genetic variation, and heredity in organisms. Though heredity had been observed for millennia, Gregor Mendel, Moravian scientist and Augustinian friar working in the 19th century in Brno, was the first to study genetics scientifically.“Genetics” is the study of how traits are inherited. A trait is defined as a variation in the physical appearance of a heritable characteristic. It seeks to understand how traits are passed from generation to generation.
Genetics is the study of how different qualities, called traits, are passed down from parents to child. Genetics helps explain what makes you unique, why family members look alike, and why some diseases run in families. When we trace the paths of these qualities, we are following packages of information called genes.DNA is found in your cell's nucleus, and you get half from each parent. Genes are DNA sequences that contain complex instructions. Just 1 percent of your DNA sequence is genes.
Genetics is one of the hardest classes I ever loved. The material is interesting and relevant.Genes are small sections of the long chain of DNA. They are the basic physical and functional units of heredity. In humans, genes vary in size from a few hundred DNA bases to more than two million bases. The Human Genome Project has estimated that humans have between 20,000 and 25,000 genes.Genetically, you actually carry more of your mother's genes than your father's. That's because of little organelles that live within your cells, the mitochondria, which you only receive from your mother.
A person inherits genes from their parents, and how parents live affects their children's genes. It's a mistaken assumption that everything you inherited in your genes is permanent. Your lifestyle and circumstances can awaken individual genes and/or suppress others.
Gregor Mendel: the 'father of genetics' In the 19th century, it was commonly believed that an organism's traits were passed on to offspring in a blend of characteristics 'donated' by each parent.
