Precise quantitative account of all types of hybrids and statistical processing of the results of experiments that he conducted for 10 years, allowed him to formulate the basic laws of heredity - the splitting and combining of hereditary "factors". Mendel showed that these factors are separated and not crossing merge and disappear. Although the crossing of two organisms with contrasting features (for example, yellow or green seeds) in the next generation of hybrids appears only one of them.</span>
