Define Law of segregation and Law of independent Assortment.

Law of segregation : Among a pair of alleles of a gene in heterozygous condition they will not blend / fuse but they segregate equally into gametes during meiosis. So chance of having dominant allele/recessive allele in a gamete will be 50%. 
Law of independent Assortment : When the plants differ from each other in two or more pairs of contrasting characters or factors then inheritance of one pair of factors is independent to that of other pair of factors. Hence four types of gametes are produced in equal proportion by dihybrid.
