He is the father of genetics. He studied inheritance in pea plants. He came up with two laws, the law of segration, and the law of independent assortment. The law of segregation states that a pair of characteristics (e.g. blue and brown eye colour) only one can be represented in a gamete. What he meant was that for any pair of characteristics there is only one gene in a gamete even though there are two genes in ordinary cells. The law of independent assortment states that for two characteristics the genes are inherited independently.If you had the genotype AaBb you would make four kinds of gametes: they would contain the combinations of either AB, Ab, aB or ab.
