Gregor Mendel was the first person to trace characteristics of generations of a living thing. His first experiments were using pea plants and the whole idea was to breed the plants and examine the generations for traits that were being passed down. He chose these plants as his experimental organisms for many reasons. Some of them being that they are capable of self pollination, easy to grow, small in size, and they reproduce quickly with many offspring. They were also capable of cross fertilizing meaning that they could mate with individuals of different kinds, such as other plants.

Therefore with his results he was able to conclude with certain laws which were named after him. The first law was the law of segregation which is broken into four parts: that alternative versions of the same gene make up for the inherited characteristics, each organism inherits two alleles (one from each parent), dominant traits are the ones expressed in the phenotype, and that each gamete contains only one allele from each parent. The second law was the law of independent assortment in which he states that the inheritance pattern of one trait will not affect the inheritance pattern of another. These were laws have all become the basics of genetics. All science revolves around these laws which make Gregol Mendel the father of genetics.
