What is empirical approach and empirical law ?

Explanation

In all Mendel.s experiments, be close two contrasing characters of single locus. He assumed that two distinct factors exist for single trait. The recessive trait does not disappear in the `F_(1)` generation and it is hidden or marked in the `F_(1)` generation and reappear in `F_(2)` generation, in which it contributes to 25% of offspring. Mendel got 3:1 ratio in `F_(2)` generation, when he crossed a homogygous dominant and recessive trait. Hence he concluded that tall and dwarf alleles of `F_(1)` heterozygote segregate randomly into gametes. Mendel is the first biological scientist to use quantitative analysis in biological research.
Mendel.s analytical approach is an outstanding scientific achievement. His breeding experiments are planned meticulously and precisely executed to show that the hereditary materials are transmitted from one generation to another. Though he ws not aware of genes during his experiments, he attributed factors, which are responsible for deciding characters. Now the factors are called genes. His approach is empirical and the laws arrived through this approach are known as empirical laws.
