Simple Mendelian Inheritance first researcher succeeded in heritage research has been the priest Gregor Mendel. Since his family merej gardening, this obviously inherit love to cultivated plants. Having studied the features of generations of peas that grow in his small garden, he concluded that the legacy is determined by several factors that exist in each individual and their descendants tejçohen. In 1866 published work "experiments with plant hybrids" where he presented the results of his work on the laws of inheritance. According to Mendel each individual feature (eg color of grains of peas) is controlled by a couple of factors. He noted that one of the factors that control the same trait, can be dominant (dominant) over another, which is recessive (the subject). An individual can be observed dominant trait (p.sh seeds yellow), while recessive factor (for green seeds), although it is present but not expressed. Mcndeli infer that the individual has on two factors that control every feature, gametes (sex cells) contain only one factor for each feature. This statement is considered as the first law of decomposition Mendelian law of segregation, during the formation of gametes in the process of separated couples mejozes factors (genes) which body cells, so each match is only one factor present find. Mendel as well crossroads head of the generation of the first individuals (F1xF1) for two traits that formula also what is called the second law of inheritance or the law of independent assortment of features "at the junction of the generation of the first individuals, alleles are divided into mrnyre independent in the form gametes, and so on gametes meet all possible combinations of alleles, as well as second generation traits breakdown occurs nevraport 3: 1 "
