Is it true that identical twins are genetically identical?

It's a basic premise of human biology that's taught in elementary schools all across the world: Identical twins are genetically identical since they are born from the same fertilised egg. It's true that identical twins have the same DNA code as one another. This is due to the fact that identical twins are made out of the same sperm and egg from their father and mother. (Fraternal twins, on the other hand, are made up of two different sperm and two different eggs.) Normally, the egg and sperm combine to form an embryo, which then develops into a human infant. Identical twins, on the other hand, divide into two embryos early in development. Instead of one baby, two are produced. According to new research, even if identical twins have highly similar genes, they are not identical. The research sheds new light on why two people who share the same embryo can have such disparities in phenotype, as biologists refer to a person's physical appearance. While the two newborns h

Difference between Genetics and Epigenetics

Epigenetics is the study of how the environment and other factors influence the expression of genes. While epigenetic modifications do not modify a person's genetic code, they can have a significant impact on their development. Epigeneticists study the mechanisms that influence gene activity. Genetics is the study of genes and the variation of characteristics that are influenced by genes—including physical and psychological characteristics. All human traits, from one's height to one's fear of heights, are driven by a complex interplay between the expression of inherited genes and feedback from the environment. Gene studies are divided into two categories: genetics and epigenetics. The main distinction between genetics and epigenetics is that genetics is concerned with genes that control body functions, whereas epigenetics is concerned with inheritable changes in organisms produced by changes in gene expression. Genes are the fundamental components of heredity that trans
