Actually, Mendelian genetics is a basic concept in genetics, relating to the passage of characters from one generation to the other. The science is named for its pioneer, Gregor Mendel, the father of genetics. The work Mendel did with pea plants warranted a whole science field being named after them. Essentially, the core of Mendelian genetics involves the laws of inheritance, especially how dominant and recessive alleles determine traits in organisms.

Mendel’s laws of inheritance form the core of Mendelian genetics. The two most renowned laws are the Law of Segregation and the Law of Independent Assortment. The Law of Segregation says that every one of us possesses a pair of alleles for each gene, which separates in the formation of gametes so that each gamete gets just one allele. The Law of Independent Assortment says why genes controlling different traits are transferred separately, along with the resultant genetic variations.

It is also applied in the study of both phenotypes and genotypes where, based on the genetic variation, it explains how it might become an expressed trait accompanied with the associated genetic configuration. Many tools such as predicting expression of certain traits in offspring associated with parental genetic makeup, the use of Punnett squares are employed.

Actually, this field has laid down a basis from which contemporary genetic research into such fields as genetic disorders, evolutionary biology and plant and animal breeding are undertaken. The principle of Mendel is also fundamental in explaining inheritance patterns and variation.
