Mendel's Law, also known as Mendelian inheritance or Genetics laws, refers to a set of principles that describe the way traits are passed from parents to offspring. These laws were first discovered by Gregor Mendel in the mid-19th century and are the foundation of modern genetics. They include the law of segregation, which states that each individual has two copies of a gene that are separated during the formation of sex cells; the law of independent assortment, which states that genes for different traits are inherited independently of each other; and the law of dominance, which states that some traits are dominant over others. These laws have been refined and expanded upon over the years, but they remain a crucial part of genetic science today.
