Gregor Mendel is often considered the father of modern Genetics. His theories were much ahead of their time and were ultimately ignored by other scientists of that time. However, later in the 20th century his work had been rediscovered and was widely accepted, later giving birth to the science of Genetics. His work had been focused around experiments on mice and flowers and he had discovered the characteristics of dominant and recessive genes which are passed onto the offspring. According to his ideas, during reproduction if two different species of the same flower or mice are crossed the result is not a hybrid but actually is favored by the presence of a dominant gene. His findings on inheritance were later summed up by him into two laws :

The Law of Segregation:
According to this law when a individuals of a species mate, the copy of their genes are separated and assorted, so that each gamete receives only one copy. Later on by the discovery of meisosis this notion was confirmed.

The Law of Independent Assortment:
This law had laid the foundation of "inheritance" which claimed that different genes assorted themselves independently of one another during gamete formation and had established the relationship between the dominant and recessive gene types.

Although, Genetics has moved far ahead than the proto ideas that had been laid down by Mendel, but still the science owes it's existence to the discovery and ideas that had originally been laid down by Mendel. We now know that the protein, phosphate and sugar chains collective double helix that exist in cells called DNA is responsible for storing and inheriting information from one species to it's offspring.
