What two laws did Gregor mandel uncover?

Gregor Mendel uncovered the Law of Segregation and the Law of Independent Assortment. The Law of Segregation states that during the formation of gametes, the two alleles for a trait separate, so each gamete carries only one allele for each gene. The Law of Independent Assortment asserts that genes for different traits are inherited independently of each other, provided the genes are on different chromosomes. These principles laid the groundwork for modern genetics.
